25 | * Amir Noam <amir.noam at intel dot com> | ||
26 | * - Added support for lacp_rate module param. | ||
27 | * | ||
28 | * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
29 | * - Based on discussion on mailing list, changed locking scheme | ||
30 | * to use lock/unlock or lock_bh/unlock_bh appropriately instead | ||
31 | * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing | ||
32 | * hidden bugs and solves system hangs that occurred due to the fact | ||
33 | * that holding lock_irqsave doesn't prevent softirqs from running. | ||
34 | * This also increases total throughput since interrupts are not | ||
35 | * blocked on each transmitted packets or monitor timeout. | ||
36 | * | ||
37 | * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
38 | * - Renamed bond_3ad_link_status_changed() to | ||
39 | * bond_3ad_handle_link_change() for compatibility with TLB. | ||
40 | * | ||
41 | * 2003/05/20 - Amir Noam <amir.noam at intel dot com> | ||
42 | * - Fix long fail over time when releasing last slave of an active | ||
43 | * aggregator - send LACPDU on unbind of slave to tell partner this | ||
44 | * port is no longer aggregatable. | ||
45 | * | ||
46 | * 2003/06/25 - Tsippy Mendelson <tsippy.mendelson at intel dot com> | ||
47 | * - Send LACPDU as highest priority packet to further fix the above | ||
48 | * problem on very high Tx traffic load where packets may get dropped | ||
49 | * by the slave. | ||
50 | * | ||
51 | * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
52 | * - Code cleanup and style changes | ||

34 | * | ||
35 | * Changes: | ||
36 | * Arnaldo Carvalho de Melo <acme@conectiva.com.br> | ||
37 | * - fix leaks on failure at bond_init | ||
38 | * | ||
39 | * 2000/09/30 - Willy Tarreau <willy at meta-x.org> | ||
40 | * - added trivial code to release a slave device. | ||
41 | * - fixed security bug (CAP_NET_ADMIN not checked) | ||
42 | * - implemented MII link monitoring to disable dead links : | ||
43 | * All MII capable slaves are checked every <miimon> milliseconds | ||
44 | * (100 ms seems good). This value can be changed by passing it to | ||
45 | * insmod. A value of zero disables the monitoring (default). | ||
46 | * - fixed an infinite loop in bond_xmit_roundrobin() when there's no | ||
47 | * good slave. | ||
48 | * - made the code hopefully SMP safe | ||
49 | * | ||
50 | * 2000/10/03 - Willy Tarreau <willy at meta-x.org> | ||
51 | * - optimized slave lists based on relevant suggestions from Thomas Davis | ||
52 | * - implemented active-backup method to obtain HA with two switches: | ||
53 | * stay as long as possible on the same active interface, while we | ||
54 | * also monitor the backup one (MII link status) because we want to know | ||
55 | * if we are able to switch at any time. ( pass "mode=1" to insmod ) | ||
56 | * - lots of stress testings because we need it to be more robust than the | ||
57 | * wires ! :-> | ||
58 | * | ||
59 | * 2000/10/09 - Willy Tarreau <willy at meta-x.org> | ||
60 | * - added up and down delays after link state change. | ||
61 | * - optimized the slaves chaining so that when we run forward, we never | ||
62 | * repass through the bond itself, but we can find it by searching | ||
63 | * backwards. Renders the deletion more difficult, but accelerates the | ||
64 | * scan. | ||
65 | * - smarter enslaving and releasing. | ||
66 | * - finer and more robust SMP locking | ||
67 | * | ||
68 | * 2000/10/17 - Willy Tarreau <willy at meta-x.org> | ||
69 | * - fixed two potential SMP race conditions | ||
70 | * | ||
71 | * 2000/10/18 - Willy Tarreau <willy at meta-x.org> | ||
72 | * - small fixes to the monitoring FSM in case of zero delays | ||
73 | * 2000/11/01 - Willy Tarreau <willy at meta-x.org> | ||
74 | * - fixed first slave not automatically used in trunk mode. | ||
75 | * 2000/11/10 : spelling of "EtherChannel" corrected. | ||
76 | * 2000/11/13 : fixed a race condition in case of concurrent accesses to ioctl(). | ||
77 | * 2000/12/16 : fixed improper usage of rtnl_exlock_nowait(). | ||
78 | * | ||
79 | * 2001/1/3 - Chad N. Tindel <ctindel at ieee dot org> | ||
80 | * - The bonding driver now simulates MII status monitoring, just like | ||
81 | * a normal network device. It will show that the link is down iff | ||
82 | * every slave in the bond shows that their links are down. If at least | ||
83 | * one slave is up, the bond's MII status will appear as up. | ||
84 | * | ||
85 | * 2001/2/7 - Chad N. Tindel <ctindel at ieee dot org> | ||
86 | * - Applications can now query the bond from user space to get | ||
87 | * information which may be useful. They do this by calling | ||
88 | * the BOND_INFO_QUERY ioctl. Once the app knows how many slaves | ||
89 | * are in the bond, it can call the BOND_SLAVE_INFO_QUERY ioctl to | ||
90 | * get slave specific information (# link failures, etc). See | ||
91 | * <linux/if_bonding.h> for more details. The structs of interest | ||
92 | * are ifbond and ifslave. | ||
93 | * | ||
94 | * 2001/4/5 - Chad N. Tindel <ctindel at ieee dot org> | ||
95 | * - Ported to 2.4 Kernel | ||
96 | * | ||
97 | * 2001/5/2 - Jeffrey E. Mast <jeff at mastfamily dot com> | ||
98 | * - When a device is detached from a bond, the slave device is no longer | ||
99 | * left thinking that is has a master. | ||
100 | * | ||
101 | * 2001/5/16 - Jeffrey E. Mast <jeff at mastfamily dot com> | ||
102 | * - memset did not appropriately initialized the bond rw_locks. Used | ||
103 | * rwlock_init to initialize to unlocked state to prevent deadlock when | ||
104 | * first attempting a lock | ||
105 | * - Called SET_MODULE_OWNER for bond device | ||
106 | * | ||
107 | * 2001/5/17 - Tim Anderson <tsa at mvista.com> | ||
108 | * - 2 paths for releasing for slave release; 1 through ioctl | ||
109 | * and 2) through close. Both paths need to release the same way. | ||
110 | * - the free slave in bond release is changing slave status before | ||
111 | * the free. The netdev_set_master() is intended to change slave state | ||
112 | * so it should not be done as part of the release process. | ||
113 | * - Simple rule for slave state at release: only the active in A/B and | ||
114 | * only one in the trunked case. | ||
115 | * | ||
116 | * 2001/6/01 - Tim Anderson <tsa at mvista.com> | ||
117 | * - Now call dev_close when releasing a slave so it doesn't screw up | ||
118 | * out routing table. | ||
119 | * | ||
120 | * 2001/6/01 - Chad N. Tindel <ctindel at ieee dot org> | ||
121 | * - Added /proc support for getting bond and slave information. | ||
122 | * Information is in /proc/net/<bond device>/info. | ||
123 | * - Changed the locking when calling bond_close to prevent deadlock. | ||
124 | * | ||
125 | * 2001/8/05 - Janice Girouard <girouard at us.ibm.com> | ||
126 | * - correct problem where refcnt of slave is not incremented in bond_ioctl | ||
127 | * so the system hangs when halting. | ||
128 | * - correct locking problem when unable to malloc in bond_enslave. | ||
129 | * - adding bond_xmit_xor logic. | ||
130 | * - adding multiple bond device support. | ||
131 | * | ||
132 | * 2001/8/13 - Erik Habbinga <erik_habbinga at hp dot com> | ||
133 | * - correct locking problem with rtnl_exlock_nowait | ||
134 | * | ||
135 | * 2001/8/23 - Janice Girouard <girouard at us.ibm.com> | ||
136 | * - bzero initial dev_bonds, to correct oops | ||
137 | * - convert SIOCDEVPRIVATE to new MII ioctl calls | ||
138 | * | ||
139 | * 2001/9/13 - Takao Indoh <indou dot takao at jp dot fujitsu dot com> | ||
140 | * - Add the BOND_CHANGE_ACTIVE ioctl implementation | ||
141 | * | ||
142 | * 2001/9/14 - Mark Huth <mhuth at mvista dot com> | ||
143 | * - Change MII_LINK_READY to not check for end of auto-negotiation, | ||
144 | * but only for an up link. | ||
145 | * | ||
146 | * 2001/9/20 - Chad N. Tindel <ctindel at ieee dot org> | ||
147 | * - Add the device field to bonding_t. Previously the net_device | ||
148 | * corresponding to a bond wasn't available from the bonding_t | ||
149 | * structure. | ||
150 | * | ||
151 | * 2001/9/25 - Janice Girouard <girouard at us.ibm.com> | ||
152 | * - add arp_monitor for active backup mode | ||
153 | * | ||
154 | * 2001/10/23 - Takao Indoh <indou dot takao at jp dot fujitsu dot com> | ||
155 | * - Various memory leak fixes | ||
156 | * | ||
157 | * 2001/11/5 - Mark Huth <mark dot huth at mvista dot com> | ||
158 | * - Don't take rtnl lock in bond_mii_monitor as it deadlocks under | ||
159 | * certain hotswap conditions. | ||
160 | * Note: this same change may be required in bond_arp_monitor ??? | ||
161 | * - Remove possibility of calling bond_sethwaddr with NULL slave_dev ptr | ||
162 | * - Handle hot swap ethernet interface deregistration events to remove | ||
163 | * kernel oops following hot swap of enslaved interface | ||
164 | * | ||
165 | * 2002/1/2 - Chad N. Tindel <ctindel at ieee dot org> | ||
166 | * - Restore original slave flags at release time. | ||
167 | * | ||
168 | * 2002/02/18 - Erik Habbinga <erik_habbinga at hp dot com> | ||
169 | * - bond_release(): calling kfree on our_slave after call to | ||
170 | * bond_restore_slave_flags, not before | ||
171 | * - bond_enslave(): saving slave flags into original_flags before | ||
172 | * call to netdev_set_master, so the IFF_SLAVE flag doesn't end | ||
173 | * up in original_flags | ||
174 | * | ||
175 | * 2002/04/05 - Mark Smith <mark.smith at comdev dot cc> and | ||
176 | * Steve Mead <steve.mead at comdev dot cc> | ||
177 | * - Port Gleb Natapov's multicast support patchs from 2.4.12 | ||
178 | * to 2.4.18 adding support for multicast. | ||
179 | * | ||
180 | * 2002/06/10 - Tony Cureington <tony.cureington * hp_com> | ||
181 | * - corrected uninitialized pointer (ifr.ifr_data) in bond_check_dev_link; | ||
182 | * actually changed function to use MIIPHY, then MIIREG, and finally | ||
183 | * ETHTOOL to determine the link status | ||
184 | * - fixed bad ifr_data pointer assignments in bond_ioctl | ||
185 | * - corrected mode 1 being reported as active-backup in bond_get_info; | ||
186 | * also added text to distinguish type of load balancing (rr or xor) | ||
187 | * - change arp_ip_target module param from "1-12s" (array of 12 ptrs) | ||
188 | * to "s" (a single ptr) | ||
189 | * | ||
190 | * 2002/08/30 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
191 | * - Removed acquisition of xmit_lock in set_multicast_list; caused | ||
192 | * deadlock on SMP (lock is held by caller). | ||
193 | * - Revamped SIOCGMIIPHY, SIOCGMIIREG portion of bond_check_dev_link(). | ||
194 | * | ||
195 | * 2002/09/18 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
196 | * - Fixed up bond_check_dev_link() (and callers): removed some magic | ||
197 | * numbers, banished local MII_ defines, wrapped ioctl calls to | ||
198 | * prevent EFAULT errors | ||
199 | * | ||
200 | * 2002/9/30 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
201 | * - make sure the ip target matches the arp_target before saving the | ||
202 | * hw address. | ||
203 | * | ||
204 | * 2002/9/30 - Dan Eisner <eisner at 2robots dot com> | ||
205 | * - make sure my_ip is set before taking down the link, since | ||
206 | * not all switches respond if the source ip is not set. | ||
207 | * | ||
208 | * 2002/10/8 - Janice Girouard <girouard at us dot ibm dot com> | ||
209 | * - read in the local ip address when enslaving a device | ||
210 | * - add primary support | ||
211 | * - make sure 2*arp_interval has passed when a new device | ||
212 | * is brought on-line before taking it down. | ||
213 | * | ||
214 | * 2002/09/11 - Philippe De Muyter <phdm at macqel dot be> | ||
215 | * - Added bond_xmit_broadcast logic. | ||
216 | * - Added bond_mode() support function. | ||
217 | * | ||
218 | * 2002/10/26 - Laurent Deniel <laurent.deniel at free.fr> | ||
219 | * - allow to register multicast addresses only on active slave | ||
220 | * (useful in active-backup mode) | ||
221 | * - add multicast module parameter | ||
222 | * - fix deletion of multicast groups after unloading module | ||
223 | * | ||
224 | * 2002/11/06 - Kameshwara Rayaprolu <kameshwara.rao * wipro_com> | ||
225 | * - Changes to prevent panic from closing the device twice; if we close | ||
226 | * the device in bond_release, we must set the original_flags to down | ||
227 | * so it won't be closed again by the network layer. | ||
228 | * | ||
229 | * 2002/11/07 - Tony Cureington <tony.cureington * hp_com> | ||
230 | * - Fix arp_target_hw_addr memory leak | ||
231 | * - Created activebackup_arp_monitor function to handle arp monitoring | ||
232 | * in active backup mode - the bond_arp_monitor had several problems... | ||
233 | * such as allowing slaves to tx arps sequentially without any delay | ||
234 | * for a response | ||
235 | * - Renamed bond_arp_monitor to loadbalance_arp_monitor and re-wrote | ||
236 | * this function to just handle arp monitoring in load-balancing mode; | ||
237 | * it is a lot more compact now | ||
238 | * - Changes to ensure one and only one slave transmits in active-backup | ||
239 | * mode | ||
240 | * - Robustesize parameters; warn users about bad combinations of | ||
241 | * parameters; also if miimon is specified and a network driver does | ||
242 | * not support MII or ETHTOOL, inform the user of this | ||
243 | * - Changes to support link_failure_count when in arp monitoring mode | ||
244 | * - Fix up/down delay reported in /proc | ||
245 | * - Added version; log version; make version available from "modinfo -d" | ||
246 | * - Fixed problem in bond_check_dev_link - if the first IOCTL (SIOCGMIIPH) | ||
247 | * failed, the ETHTOOL ioctl never got a chance | ||
248 | * | ||
249 | * 2002/11/16 - Laurent Deniel <laurent.deniel at free.fr> | ||
250 | * - fix multicast handling in activebackup_arp_monitor | ||
251 | * - remove one unnecessary and confusing curr_active_slave == slave test | ||
252 | * in activebackup_arp_monitor | ||
253 | * | ||
254 | * 2002/11/17 - Laurent Deniel <laurent.deniel at free.fr> | ||
255 | * - fix bond_slave_info_query when slave_id = num_slaves | ||
256 | * | ||
257 | * 2002/11/19 - Janice Girouard <girouard at us dot ibm dot com> | ||
258 | * - correct ifr_data reference. Update ifr_data reference | ||
259 | * to mii_ioctl_data struct values to avoid confusion. | ||
260 | * | ||
261 | * 2002/11/22 - Bert Barbe <bert.barbe at oracle dot com> | ||
262 | * - Add support for multiple arp_ip_target | ||
263 | * | ||
264 | * 2002/12/13 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
265 | * - Changed to allow text strings for mode and multicast, e.g., | ||
266 | * insmod bonding mode=active-backup. The numbers still work. | ||
267 | * One change: an invalid choice will cause module load failure, | ||
268 | * rather than the previous behavior of just picking one. | ||
269 | * - Minor cleanups; got rid of dup ctype stuff, atoi function | ||
270 | * | ||
271 | * 2003/02/07 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
272 | * - Added use_carrier module parameter that causes miimon to | ||
273 | * use netif_carrier_ok() test instead of MII/ETHTOOL ioctls. | ||
274 | * - Minor cleanups; consolidated ioctl calls to one function. | ||
275 | * | ||
276 | * 2003/02/07 - Tony Cureington <tony.cureington * hp_com> | ||
277 | * - Fix bond_mii_monitor() logic error that could result in | ||
278 | * bonding round-robin mode ignoring links after failover/recovery | ||
279 | * | ||
280 | * 2003/03/17 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
281 | * - kmalloc fix (GFP_KERNEL to GFP_ATOMIC) reported by | ||
282 | * Shmulik dot Hen at intel.com. | ||
283 | * - Based on discussion on mailing list, changed use of | ||
284 | * update_slave_cnt(), created wrapper functions for adding/removing | ||
285 | * slaves, changed bond_xmit_xor() to check slave_cnt instead of | ||
286 | * checking slave and slave->dev (which only worked by accident). | ||
287 | * - Misc code cleanup: get arp_send() prototype from header file, | ||
288 | * add max_bonds to bonding.txt. | ||
289 | * | ||
290 | * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | ||
291 | * Shmulik Hen <shmulik.hen at intel dot com> | ||
292 | * - Make sure only bond_attach_slave() and bond_detach_slave() can | ||
293 | * manipulate the slave list, including slave_cnt, even when in | ||
294 | * bond_release_all(). | ||
295 | * - Fixed hang in bond_release() with traffic running: | ||
296 | * netdev_set_master() must not be called from within the bond lock. | ||
297 | * | ||
298 | * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | ||
299 | * Shmulik Hen <shmulik.hen at intel dot com> | ||
300 | * - Fixed hang in bond_enslave() with traffic running: | ||
301 | * netdev_set_master() must not be called from within the bond lock. | ||
302 | * | ||
303 | * 2003/03/18 - Amir Noam <amir.noam at intel dot com> | ||
304 | * - Added support for getting slave's speed and duplex via ethtool. | ||
305 | * Needed for 802.3ad and other future modes. | ||
306 | * | ||
307 | * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | ||
308 | * Shmulik Hen <shmulik.hen at intel dot com> | ||
309 | * - Enable support of modes that need to use the unique mac address of | ||
310 | * each slave. | ||
311 | * * bond_enslave(): Moved setting the slave's mac address, and | ||
312 | * openning it, from the application to the driver. This breaks | ||
313 | * backward comaptibility with old versions of ifenslave that open | ||
314 | * the slave before enalsving it !!!. | ||
315 | * * bond_release(): The driver also takes care of closing the slave | ||
316 | * and restoring its original mac address. | ||
317 | * - Removed the code that restores all base driver's flags. | ||
318 | * Flags are automatically restored once all undo stages are done | ||
319 | * properly. | ||
320 | * - Block possibility of enslaving before the master is up. This | ||
321 | * prevents putting the system in an unstable state. | ||
322 | * | ||
323 | * 2003/03/18 - Amir Noam <amir.noam at intel dot com>, | ||
324 | * Tsippy Mendelson <tsippy.mendelson at intel dot com> and | ||
325 | * Shmulik Hen <shmulik.hen at intel dot com> | ||
326 | * - Added support for IEEE 802.3ad Dynamic link aggregation mode. | ||
327 | * | ||
328 | * 2003/05/01 - Amir Noam <amir.noam at intel dot com> | ||
329 | * - Added ABI version control to restore compatibility between | ||
330 | * new/old ifenslave and new/old bonding. | ||
331 | * | ||
332 | * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
333 | * - Fixed bug in bond_release_all(): save old value of curr_active_slave | ||
334 | * before setting it to NULL. | ||
335 | * - Changed driver versioning scheme to include version number instead | ||
336 | * of release date (that is already in another field). There are 3 | ||
337 | * fields X.Y.Z where: | ||
338 | * X - Major version - big behavior changes | ||
339 | * Y - Minor version - addition of features | ||
340 | * Z - Extra version - minor changes and bug fixes | ||
341 | * The current version is 1.0.0 as a base line. | ||
342 | * | ||
343 | * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and | ||
344 | * Amir Noam <amir.noam at intel dot com> | ||
345 | * - Added support for lacp_rate module param. | ||
346 | * - Code beautification and style changes (mainly in comments). | ||
347 | * new version - 1.0.1 | ||
348 | * | ||
349 | * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
350 | * - Based on discussion on mailing list, changed locking scheme | ||
351 | * to use lock/unlock or lock_bh/unlock_bh appropriately instead | ||
352 | * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing | ||
353 | * hidden bugs and solves system hangs that occurred due to the fact | ||
354 | * that holding lock_irqsave doesn't prevent softirqs from running. | ||
355 | * This also increases total throughput since interrupts are not | ||
356 | * blocked on each transmitted packets or monitor timeout. | ||
357 | * new version - 2.0.0 | ||
358 | * | ||
359 | * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
360 | * - Added support for Transmit load balancing mode. | ||
361 | * - Concentrate all assignments of curr_active_slave to a single point | ||
362 | * so specific modes can take actions when the primary adapter is | ||
363 | * changed. | ||
364 | * - Take the updelay parameter into consideration during bond_enslave | ||
365 | * since some adapters loose their link during setting the device. | ||
366 | * - Renamed bond_3ad_link_status_changed() to | ||
367 | * bond_3ad_handle_link_change() for compatibility with TLB. | ||
368 | * new version - 2.1.0 | ||
369 | * | ||
370 | * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> | ||
371 | * - Added support for Adaptive load balancing mode which is | ||
372 | * equivalent to Transmit load balancing + Receive load balancing. | ||
373 | * new version - 2.2.0 | ||
374 | * | ||
375 | * 2003/05/15 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
376 | * - Applied fix to activebackup_arp_monitor posted to bonding-devel | ||
377 | * by Tony Cureington <tony.cureington * hp_com>. Fixes ARP | ||
378 | * monitor endless failover bug. Version to 2.2.10 | ||
379 | * | ||
380 | * 2003/05/20 - Amir Noam <amir.noam at intel dot com> | ||
381 | * - Fixed bug in ABI version control - Don't commit to a specific | ||
382 | * ABI version if receiving unsupported ioctl commands. | ||
383 | * | ||
384 | * 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com> | ||
385 | * - Fix ifenslave -c causing bond to loose existing routes; | ||
386 | * added bond_set_mac_address() that doesn't require the | ||
387 | * bond to be down. | ||
388 | * - In conjunction with fix for ifenslave -c, in | ||
389 | * bond_change_active(), changing to the already active slave | ||
390 | * is no longer an error (it successfully does nothing). | ||
391 | * | ||
392 | * 2003/06/30 - Amir Noam <amir.noam at intel dot com> | ||
393 | * - Fixed bond_change_active() for ALB/TLB modes. | ||
394 | * Version to 2.2.14. | ||
395 | * | ||
396 | * 2003/07/29 - Amir Noam <amir.noam at intel dot com> | ||
397 | * - Fixed ARP monitoring bug. | ||
398 | * Version to 2.2.15. | ||
399 | * | ||
400 | * 2003/07/31 - Willy Tarreau <willy at ods dot org> | ||
401 | * - Fixed kernel panic when using ARP monitoring without | ||
402 | * setting bond's IP address. | ||
403 | * Version to 2.2.16. | ||
404 | * | ||
405 | * 2003/08/06 - Amir Noam <amir.noam at intel dot com> | ||
406 | * - Back port from 2.6: use alloc_netdev(); fix /proc handling; | ||
407 | * made stats a part of bond struct so no need to allocate | ||
408 | * and free it separately; use standard list operations instead | ||
409 | * of pre-allocated array of bonds. | ||
410 | * Version to 2.3.0. | ||
411 | * | ||
412 | * 2003/08/07 - Jay Vosburgh <fubar at us dot ibm dot com>, | ||
413 | * Amir Noam <amir.noam at intel dot com> and | ||
414 | * Shmulik Hen <shmulik.hen at intel dot com> | ||
415 | * - Propagating master's settings: Distinguish between modes that | ||
416 | * use a primary slave from those that don't, and propagate settings | ||
417 | * accordingly; Consolidate change_active opeartions and add | ||
418 | * reselect_active and find_best opeartions; Decouple promiscuous | ||
419 | * handling from the multicast mode setting; Add support for changing | ||
420 | * HW address and MTU with proper unwind; Consolidate procfs code, | ||
421 | * add CHANGENAME handler; Enhance netdev notification handling. | ||
422 | * Version to 2.4.0. | ||
423 | * | ||
424 | * 2003/09/15 - Stephen Hemminger <shemminger at osdl dot org>, | ||
425 | * Amir Noam <amir.noam at intel dot com> | ||
426 | * - Convert /proc to seq_file interface. | ||
427 | * Change /proc/net/bondX/info to /proc/net/bonding/bondX. | ||
428 | * Set version to 2.4.1. | ||
429 | * | ||
430 | * 2003/11/20 - Amir Noam <amir.noam at intel dot com> | ||
431 | * - Fix /proc creation/destruction. | ||
432 | * | ||
433 | * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com> | ||
434 | * - Massive cleanup - Set version to 2.5.0 | ||
435 | * Code changes: | ||
436 | * o Consolidate format of prints and debug prints. | ||

438 | * o Remove dead code and unnecessary checks. | ||
439 | * o Consolidate starting/stopping timers. | ||
440 | * o Consolidate handling of primary module param throughout the code. | ||
441 | * o Removed multicast module param support - all settings are done | ||
442 | * according to mode. | ||
443 | * o Slave list iteration - bond is no longer part of the list, | ||
444 | * added cyclic list iteration macros. | ||
445 | * o Consolidate error handling in all xmit functions. | ||
446 | * Style changes: | ||
447 | * o Consolidate function naming and declarations. | ||
448 | * o Consolidate function params and local variables names. | ||
449 | * o Consolidate return values. | ||
450 | * o Consolidate curly braces. | ||
451 | * o Consolidate conditionals format. | ||
452 | * o Change struct member names and types. | ||

455 | * | ||
456 | * 2003/12/30 - Amir Noam <amir.noam at intel dot com> | ||
457 | * - Fixed: Cannot remove and re-enslave the original active slave. | ||
458 | * - Fixed: Releasing the original active slave causes mac address | ||
459 | * duplication. | ||
460 | * - Add support for slaves that use ethtool_ops. | ||
461 | * Set version to 2.5.3. | ||
462 | * | ||

469 | * * Add support for VLAN hardware acceleration capable slaves. | ||
470 | * * Add capability to tag self generated packets in ALB/TLB modes. | ||
471 | * Set version to 2.6.0. | ||
472 | * 2004/10/29 - Mitch Williams <mitch.a.williams at intel dot com> | ||
473 | * - Fixed bug when unloading module while using 802.3ad. If | ||
474 | * spinlock debugging is turned on, this causes a stack dump. | ||
475 | * Solution is to move call to dev_remove_pack outside of the | ||
476 | * spinlock. | ||
477 | * Set version to 2.6.1. | ||
478 | * 2005/06/05 - Jay Vosburgh <fubar@us.ibm.com> | ||
479 | * - Support for generating gratuitous ARPs in active-backup mode. | ||

482 | * 2005/06/08 - Jason Gabler <jygabler at lbl dot gov> | ||
483 | * - alternate hashing policy support for mode 2 | ||
484 | * * Added kernel parameter "xmit_hash_policy" to allow the selection | ||
485 | * of different hashing policies for mode 2. The original mode 2 | ||
486 | * policy is the default, now found in xmit_hash_policy_layer2(). | ||
487 | * * Added xmit_hash_policy_layer34() | ||
488 | * - Modified by Jay Vosburgh <fubar@us.ibm.com> to also support mode 4. | ||
489 | * Set version to 2.6.3. | ||
490 | * 2005/09/26 - Jay Vosburgh <fubar@us.ibm.com> | ||
491 | * - Removed backwards compatibility for old ifenslaves. Version 2.6.4. | ||

11 | * Assumptions made in this code: | ||
12 | * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where | ||
13 | * only one full element list is used. This includes, for example, | ||
14 | * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This | ||
15 | * is not an exhaustive list.) | ||
16 | * - The RBUF uses 64-byte mpackets. | ||
17 | * - RX descriptors reside in SRAM, and have the following format: | ||
18 | * struct rx_desc | ||
19 | * { | ||
20 | * // to uengine | ||
21 | * u32 buf_phys_addr; | ||
22 | * u32 buf_length; | ||
23 | * | ||
24 | * // from uengine | ||
25 | * u32 channel; | ||
26 | * u32 pkt_length; | ||
27 | * }; | ||
28 | * - Packet data resides in DRAM. | ||
29 | * - Packet buffer addresses are 8-byte aligned. | ||
30 | * - Scratch ring 0 is rx_pending. | ||
31 | * - Scratch ring 1 is rx_done, and has status condition 'full'. | ||
32 | * - The host triggers rx_done flush and rx_pending refill on seeing INTA. | ||
33 | * - This code is run on all eight threads of the microengine it runs on. | ||
34 | * | ||
35 | * Local memory is used for per-channel RX state. | ||

10 | * | ||
11 | * Assumptions made in this code: | ||
12 | * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where | ||
13 | * only one TBUF partition is used. This includes, for example, | ||
14 | * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This | ||
15 | * is not an exhaustive list.) | ||
16 | * - The TBUF uses 64-byte mpackets. | ||
17 | * - TX descriptors reside in SRAM, and have the following format: | ||
18 | * struct tx_desc | ||
19 | * { | ||
20 | * // to uengine | ||
21 | * u32 buf_phys_addr; | ||
22 | * u32 pkt_length; | ||
23 | * u32 channel; | ||
24 | * }; | ||
25 | * - Packet data resides in DRAM. | ||
26 | * - Packet buffer addresses are 8-byte aligned. | ||
27 | * - Scratch ring 2 is tx_pending. | ||
28 | * - Scratch ring 3 is tx_done, and has status condition 'full'. | ||
29 | * - This code is run on all eight threads of the microengine it runs on. | ||
