22 * BITMAP UNPLUGGING:
23 *
24 * The sequencing for updating the bitmap reliably is a little
25 * subtle (and I got it wrong the first time) so it deserves some
26 * explanation.
27 *
28 * We group bitmap updates into batches. Each batch has a number.
29 * We may write out several batches at once, but that isn't very important.
30 * conf->bm_write is the number of the last batch successfully written.
31 * conf->bm_flush is the number of the last batch that was closed to
32 * new additions.
33 * When we discover that we will need to write to any block in a stripe
34 * (in add_stripe_bio) we update the in-memory bitmap and record in sh->bm_seq
35 * the number of the batch it will be in. This is bm_flush+1.
36 * When we are ready to do a write, if that batch hasn't been written yet,
37 * we plug the array and queue the stripe for later.
38 * When an unplug happens, we increment bm_flush, thus closing the current
39 * batch.
40 * When we notice that bm_flush > bm_write, we write out all pending updates
41 * to the bitmap, and advance bm_write to where bm_flush was.
42 * This may occasionally write a bit out twice, but is sure never to
43 * miss any bits.

20 Linux Kernel Additions:
21
22 0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
23 0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
24 Remove compatibility defines for kernel versions < 2.2.x.
25 Update for new 2.3.x module interface
26 LK1.1.2 (March 19, 2000)
27 * New PCI interface (jgarzik)
28
29 LK1.1.3 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
30 - Merged with 3c575_cb.c
31 - Don't set RxComplete in boomerang interrupt enable reg
32 - spinlock in vortex_timer to protect mdio functions
33 - disable local interrupts around call to vortex_interrupt in
34 vortex_tx_timeout() (So vortex_interrupt can use spin_lock())
35 - Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
36 - In vortex_start_xmit(), move the lock to _after_ we've altered
37 vp->cur_tx and vp->tx_full. This defeats the race between
38 vortex_start_xmit() and vortex_interrupt which was identified
39 by Bogdan Costescu.
40 - Merged back support for six new cards from various sources
41 - Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
42 insertion oops)
43 - Tell it that 3c905C has NWAY for 100bT autoneg
44 - Fix handling of SetStatusEnd in 'Too much work..' code, as
45 per 2.3.99's 3c575_cb (Dave Hinds).
46 - Split ISR into two for vortex & boomerang
47 - Fix MOD_INC/DEC races
48 - Handle resource allocation failures.
49 - Fix 3CCFE575CT LED polarity
50 - Make tx_interrupt_mitigation the default
51
52 LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
53 - Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
54 - Put vortex_info_tbl into __devinitdata
55 - In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
56 as in the hardware.
57 - Increased the loop counter in issue_and_wait from 2,000 to 4,000.
58
59 LK1.1.5 28 April 2000, andrewm
60 - Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
61 - Some extra diagnostics
62 - In vortex_error(), reset the Tx on maxCollisions. Otherwise most
63 chips usually get a Tx timeout.
64 - Added extra_reset module parm
65 - Replaced some inline timer manip with mod_timer
66 (Franois romieu <Francois.Romieu@nic.fr>)
67 - In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
68 (this came across from 3c575_cb).
69
70 LK1.1.6 06 Jun 2000, andrewm
71 - Backed out the PPC defines.
72 - Use del_timer_sync(), mod_timer().
73 - Fix wrapped ulong comparison in boomerang_rx()
74 - Add IS_TORNADO, use it to suppress 3c905C checksum error msg
75 (Donald Becker, I Lee Hetherington <ilh@sls.lcs.mit.edu>)
76 - Replace union wn3_config with BFINS/BFEXT manipulation for
77 sparc64 (Pete Zaitcev, Peter Jones)
78 - In vortex_error, do_tx_reset and vortex_tx_timeout(Vortex):
79 do a netif_wake_queue() to better recover from errors. (Anders Pedersen,
80 Donald Becker)
81 - Print a warning on out-of-memory (rate limited to 1 per 10 secs)
82 - Added two more Cardbus 575 NICs: 5b57 and 6564 (Paul Wagland)
83
84 LK1.1.7 2 Jul 2000 andrewm
85 - Better handling of shared IRQs
86 - Reset the transmitter on a Tx reclaim error
87 - Fixed crash under OOM during vortex_open() (Mark Hemment)
88 - Fix Rx cessation problem during OOM (help from Mark Hemment)
89 - The spinlocks around the mdio access were blocking interrupts for 300uS.
90 Fix all this to use spin_lock_bh() within mdio_read/write
91 - Only write to TxFreeThreshold if it's a boomerang - other NICs don't
92 have one.
93 - Added 802.3x MAC-layer flow control support
94
95 LK1.1.8 13 Aug 2000 andrewm
96 - Ignore request_region() return value - already reserved if Cardbus.
97 - Merged some additional Cardbus flags from Don's 0.99Qk
98 - Some fixes for 3c556 (Fred Maciel)
99 - Fix for EISA initialisation (Jan Rekorajski)
100 - Renamed MII_XCVR_PWR and EEPROM_230 to align with 3c575_cb and D. Becker's drivers
101 - Fixed MII_XCVR_PWR for 3CCFE575CT
102 - Added INVERT_LED_PWR, used it.
103 - Backed out the extra_reset stuff
104
105 LK1.1.9 12 Sep 2000 andrewm
106 - Backed out the tx_reset_resume flags. It was a no-op.
107 - In vortex_error, don't reset the Tx on txReclaim errors
108 - In vortex_error, don't reset the Tx on maxCollisions errors.
109 Hence backed out all the DownListPtr logic here.
110 - In vortex_error, give Tornado cards a partial TxReset on
111 maxCollisions (David Hinds). Defined MAX_COLLISION_RESET for this.
112 - Redid some driver flags and device names based on pcmcia_cs-3.1.20.
113 - Fixed a bug where, if vp->tx_full is set when the interface
114 is downed, it remains set when the interface is upped. Bad
115 things happen.
116
117 LK1.1.10 17 Sep 2000 andrewm
118 - Added EEPROM_8BIT for 3c555 (Fred Maciel)
119 - Added experimental support for the 3c556B Laptop Hurricane (Louis Gerbarg)
120 - Add HAS_NWAY to "3c900 Cyclone 10Mbps TPO"
121
122 LK1.1.11 13 Nov 2000 andrewm
123 - Dump MOD_INC/DEC_USE_COUNT, use SET_MODULE_OWNER
124
125 LK1.1.12 1 Jan 2001 andrewm (2.4.0-pre1)
126 - Call pci_enable_device before we request our IRQ (Tobias Ringstrom)
127 - Add 3c590 PCI latency timer hack to vortex_probe1 (from 0.99Ra)
128 - Added extended issue_and_wait for the 3c905CX.
129 - Look for an MII on PHY index 24 first (3c905CX oddity).
130 - Add HAS_NWAY to 3cSOHO100-TX (Brett Frankenberger)
131 - Don't free skbs we don't own on oom path in vortex_open().
132
133 LK1.1.13 27 Jan 2001
134 - Added explicit `medialock' flag so we can truly
135 lock the media type down with `options'.
136 - "check ioremap return and some tidbits" (Arnaldo Carvalho de Melo <acme@conectiva.com.br>)
137 - Added and used EEPROM_NORESET for 3c556B PM resumes.
138 - Fixed leakage of vp->rx_ring.
139 - Break out separate HAS_HWCKSM device capability flag.
140 - Kill vp->tx_full (ANK)
141 - Merge zerocopy fragment handling (ANK?)
142
143 LK1.1.14 15 Feb 2001
144 - Enable WOL. Can be turned on with `enable_wol' module option.
145 - EISA and PCI initialisation fixes (jgarzik, Manfred Spraul)
146 - If a device's internalconfig register reports it has NWAY,
147 use it, even if autoselect is enabled.
148
149 LK1.1.15 6 June 2001 akpm
150 - Prevent double counting of received bytes (Lars Christensen)
151 - Add ethtool support (jgarzik)
152 - Add module parm descriptions (Andrzej M. Krzysztofowicz)
153 - Implemented alloc_etherdev() API
154 - Special-case the 'Tx error 82' message.

157 - Make NETIF_F_SG dependent upon nr_free_highpages(), not on CONFIG_HIGHMEM
158 - Lessen verbosity of bootup messages
159 - Fix WOL - use new PM API functions.
160 - Use netif_running() instead of vp->open in suspend/resume.
161 - Don't reset the interface logic on open/close/rmmod. It upsets
162 autonegotiation, and hence DHCP (from 0.99T).
163 - Back out EEPROM_NORESET flag because of the above (we do it for all
164 NICs).
165 - Correct 3c982 identification string
166 - Rename wait_for_completion() to issue_and_wait() to avoid completion.h
167 clash.
168
169 LK1.1.17 18Dec01 akpm
170 - PCI ID 9805 is a Python-T, not a dual-port Cyclone. Apparently.
171 And it has NWAY.
172 - Mask our advertised modes (vp->advertising) with our capabilities
173 (MII reg5) when deciding which duplex mode to use.
174 - Add `global_options' as default for options[]. Ditto global_enable_wol,
175 global_full_duplex.
176
177 LK1.1.18 01Jul02 akpm
178 - Fix for undocumented transceiver power-up bit on some 3c566B's
179 (Donald Becker, Rahul Karnik)
180
181 - See http://www.zip.com.au/~akpm/linux/#3c59x-2.3 for more details.
182 - Also see Documentation/networking/vortex.txt
183
184 LK1.1.19 10Nov02 Marc Zyngier <maz@wild-wind.fr.eu.org>
185 - EISA sysfs integration.

24 25
25 Linux kernel modifications:
26
27 Version 1.0.1:
28 - Spinlock fixes
29 - Bug fixes and better intr performance (Tjeerd)
30 Version 1.0.2:
31 - Now reads correct MAC address from eeprom
32 Version 1.0.3:
33 - Eliminate redundant priv->tx_full flag
34 - Call netif_start_queue from dev->tx_timeout
35 - wmb() in start_tx() to flush data
36 - Update Tx locking
37 - Clean up PCI enable (davej)
38 Version 1.0.4:
39 - Merge Donald Becker's natsemi.c version 1.07
40 Version 1.0.5:
41 - { fill me in }
42 Version 1.0.6:
43 * ethtool support (jgarzik)
44 * Proper initialization of the card (which sometimes
45 fails to occur and leaves the card in a non-functional
46 state). (uzi)
47
48 * Some documented register settings to optimize some
49 of the 100Mbit autodetection circuitry in rev C cards. (uzi)
50
51 * Polling of the PHY intr for stuff like link state
52 change and auto- negotiation to finally work properly. (uzi)
53
54 * One-liner removal of a duplicate declaration of
55 netdev_error(). (uzi)
56
57 Version 1.0.7: (Manfred Spraul)
58 * pci dma
59 * SMP locking update
60 * full reset added into tx_timeout
61 * correct multicast hash generation (both big and little endian)
62 [copied from a natsemi driver version
63 from Myrio Corporation, Greg Smith]
64 * suspend/resume
65
66 version 1.0.8 (Tim Hockin <thockin@sun.com>)
67 * ETHTOOL_* support
68 * Wake on lan support (Erik Gilling)
69 * MXDMA fixes for serverworks
70 * EEPROM reload
71
72 version 1.0.9 (Manfred Spraul)
73 * Main change: fix lack of synchronize
74 netif_close/netif_suspend against a last interrupt
75 or packet.
76 * do not enable superflous interrupts (e.g. the
77 drivers relies on TxDone - TxIntr not needed)
78 * wait that the hardware has really stopped in close
79 and suspend.
80 * workaround for the (at least) gcc-2.95.1 compiler
81 problem. Also simplifies the code a bit.
82 * disable_irq() in tx_timeout - needed to protect
83 against rx interrupts.
84 * stop the nic before switching into silent rx mode
85 for wol (required according to docu).
86
87 version 1.0.10:
88 * use long for ee_addr (various)
89 * print pointers properly (DaveM)
90 * include asm/irq.h (?)
91
92 version 1.0.11:
93 * check and reset if PHY errors appear (Adrian Sun)
94 * WoL cleanup (Tim Hockin)
95 * Magic number cleanup (Tim Hockin)
96 * Don't reload EEPROM on every reset (Tim Hockin)
97 * Save and restore EEPROM state across reset (Tim Hockin)
98 * MDIO Cleanup (Tim Hockin)
99 * Reformat register offsets/bits (jgarzik)
100
101 version 1.0.12:
102 * ETHTOOL_* further support (Tim Hockin)
103
104 version 1.0.13:
105 * ETHTOOL_[G]EEPROM support (Tim Hockin)
106
107 version 1.0.13:
108 * crc cleanup (Matt Domsch <Matt_Domsch@dell.com>)
109
110 version 1.0.14:
111 * Cleanup some messages and autoneg in ethtool (Tim Hockin)
112
113 version 1.0.15:
114 * Get rid of cable_magic flag
115 * use new (National provided) solution for cable magic issue
116
117 version 1.0.16:
118 * call netdev_rx() for RxErrors (Manfred Spraul)
119 * formatting and cleanups
120 * change options and full_duplex arrays to be zero
121 initialized
122 * enable only the WoL and PHY interrupts in wol mode
123
124 version 1.0.17:
125 * only do cable_magic on 83815 and early 83816 (Tim Hockin)
126 * create a function for rx refill (Manfred Spraul)
127 * combine drain_ring and init_ring (Manfred Spraul)
128 * oom handling (Manfred Spraul)
129 * hands_off instead of playing with netif_device_{de,a}ttach
130 (Manfred Spraul)
131 * be sure to write the MAC back to the chip (Manfred Spraul)
132 * lengthen EEPROM timeout, and always warn about timeouts
133 (Manfred Spraul)
134 * comments update (Manfred)
135 * do the right thing on a phy-reset (Manfred and Tim)

30 Linux kernel version history:
31
32 LK1.1.0:
33 - Jeff Garzik: softnet 'n stuff
34
35 LK1.1.1:
36 - Justin Guyett: softnet and locking fixes
37 - Jeff Garzik: use PCI interface
38
39 LK1.1.2:
40 - Urban Widmark: minor cleanups, merges from Becker 1.03a/1.04 versions
41
42 LK1.1.3:
43 - Urban Widmark: use PCI DMA interface (with thanks to the eepro100.c
44 code) update "Theory of Operation" with
45 softnet/locking changes
46 - Dave Miller: PCI DMA and endian fixups
47 - Jeff Garzik: MOD_xxx race fixes, updated PCI resource allocation
48
49 LK1.1.4:
50 - Urban Widmark: fix gcc 2.95.2 problem and
51 remove writel's to fixed address 0x7c
52
53 LK1.1.5:
54 - Urban Widmark: mdio locking, bounce buffer changes
55 merges from Beckers 1.05 version
56 added netif_running_on/off support
57
58 LK1.1.6:
59 - Urban Widmark: merges from Beckers 1.08b version (VT6102 + mdio)
60 set netif_running_on/off on startup, del_timer_sync
61
62 LK1.1.7:
63 - Manfred Spraul: added reset into tx_timeout
64
65 LK1.1.9:
66 - Urban Widmark: merges from Beckers 1.10 version
67 (media selection + eeprom reload)
68 - David Vrabel: merges from D-Link "1.11" version
69 (disable WOL and PME on startup)
70
71 LK1.1.10:
72 - Manfred Spraul: use "singlecopy" for unaligned buffers
73 don't allocate bounce buffers for !ReqTxAlign cards
74
75 LK1.1.11:
76 - David Woodhouse: Set dev->base_addr before the first time we call
77 wait_for_reset(). It's a lot happier that way.
78 Free np->tx_bufs only if we actually allocated it.
79
80 LK1.1.12:
81 - Martin Eriksson: Allow Memory-Mapped IO to be enabled.
82
83 LK1.1.13 (jgarzik):
84 - Add ethtool support
85 - Replace some MII-related magic numbers with constants
86
87 LK1.1.14 (Ivan G.):
88 - fixes comments for Rhine-III
89 - removes W_MAX_TIMEOUT (unused)
90 - adds HasDavicomPhy for Rhine-I (basis: linuxfet driver; my card
91 is R-I and has Davicom chip, flag is referenced in kernel driver)
92 - sends chip_id as a parameter to wait_for_reset since np is not
93 initialized on first call
94 - changes mmio "else if (chip_id==VT6102)" to "else" so it will work
95 for Rhine-III's (documentation says same bit is correct)
96 - transmit frame queue message is off by one - fixed
97 - adds IntrNormalSummary to "Something Wicked" exclusion list
98 so normal interrupts will not trigger the message (src: Donald Becker)
99 (Roger Luethi)
100 - show confused chip where to continue after Tx error
101 - location of collision counter is chip specific
102 - allow selecting backoff algorithm (module parameter)
103
104 LK1.1.15 (jgarzik):
105 - Use new MII lib helper generic_mii_ioctl
106
107 LK1.1.16 (Roger Luethi)
108 - Etherleak fix
109 - Handle Tx buffer underrun
110 - Fix bugs in full duplex handling
111 - New reset code uses "force reset" cmd on Rhine-II
112 - Various clean ups
113
114 LK1.1.17 (Roger Luethi)
115 - Fix race in via_rhine_start_tx()
116 - On errors, wait for Tx engine to turn off before scavenging
117 - Handle Tx descriptor write-back race on Rhine-II
118 - Force flushing for PCI posted writes
119 - More reset code changes
120
121 LK1.1.18 (Roger Luethi)
122 - No filtering multicast in promisc mode (Edward Peng)
123 - Fix for Rhine-I Tx timeouts
124
125 LK1.1.19 (Roger Luethi)
126 - Increase Tx threshold for unspecified errors
127
128 LK1.2.0-2.6 (Roger Luethi)
129 - Massive clean-up
130 - Rewrite PHY, media handling (remove options, full_duplex, backoff)
131 - Fix Tx engine race for good
132 - Craig Brind: Zero padded aligned buffers for short packets.

246 * Certain PCI motherboards will scan PCI devices from highest to lowest,

248 * strange things when they come into contact with PCI bridge chips. The
249 * net result of all this is that the PCI card that is actually used to boot
250 * the machine is very hard to detect. Most motherboards go from lowest
251 * PCI slot number to highest, and the first SCSI controller found is the
252 * one you boot from. The only exceptions to this are when a controller
253 * has its BIOS disabled. So, we by default sort all of our SCSI controllers
254 * from lowest PCI slot number to highest PCI slot number. We also force
255 * all controllers with their BIOS disabled to the end of the list. This
256 * works on *almost* all computers. Where it doesn't work, we have this
257 * option. Setting this option to non-0 will reverse the order of the sort
258 * to highest first, then lowest, but will still leave cards with their BIOS
259 * disabled at the very end. That should fix everyone up unless there are
260 * really strange cirumstances.

14 2005-05-19 v0.1 Initial version, based on incomplete docs
15 and analysis of misbehavior with the standard driver
16 2005-05-20 v0.2 Extended the input buffer to avoid losing
17 random 64-byte chunks of data
18 2005-05-21 v0.3 implemented chars_in_buffer()
19 turned on low_latency
20 simplified the code somewhat
21 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load
22 removed some dead code
23 added sponsor notice
24 coding style clean-up
25 2005-06-20 v0.4.1 add missing braces :-/
26 killed end-of-line whitespace
27 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2
28 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard
29 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes
30 wants to send >2000 bytes.
31 2006-04-10 v0.5 fixed two array overrun errors :-/
32 2006-04-21 v0.5.1 added support for Sierra Wireless MC8755
33 2006-05-15 v0.6 re-enable multi-port support
34 2006-06-01 v0.6.1 add COBRA
35 2006-06-01 v0.6.2 add backwards-compatibility stuff
36 2006-06-01 v0.6.3 add Novatel Wireless

154 * usb_serial_driver - describes a usb serial driver
155 * @description: pointer to a string that describes this driver. This string used
156 * in the syslog messages when a device is inserted or removed.
157 * @id_table: pointer to a list of usb_device_id structures that define all
158 * of the devices this structure can support.
159 * @num_interrupt_in: the number of interrupt in endpoints this device will
160 * have.
161 * @num_interrupt_out: the number of interrupt out endpoints this device will
162 * have.
163 * @num_bulk_in: the number of bulk in endpoints this device will have.
164 * @num_bulk_out: the number of bulk out endpoints this device will have.
165 * @num_ports: the number of different ports this device will have.
166 * @calc_num_ports: pointer to a function to determine how many ports this
167 * device has dynamically. It will be called after the probe()
168 * callback is called, but before attach()
169 * @probe: pointer to the driver's probe function.
170 * This will be called when the device is inserted into the system,
171 * but before the device has been fully initialized by the usb_serial
172 * subsystem. Use this function to download any firmware to the device,
173 * or any other early initialization that might be needed.
174 * Return 0 to continue on with the initialization sequence. Anything
175 * else will abort it.
176 * @attach: pointer to the driver's attach function.
177 * This will be called when the struct usb_serial structure is fully set
178 * set up. Do any local initialization of the device, or any private
179 * memory structure allocation at this point in time.
180 * @shutdown: pointer to the driver's shutdown function. This will be
181 * called when the device is removed from the system.
182 *
183 * This structure is defines a USB Serial driver. It provides all of
184 * the information that the USB serial core code needs. If the function
185 * pointers are defined, then the USB serial core code will call them when
186 * the corresponding tty port functions are called. If they are not
187 * called, the generic serial function will be used instead.
188 *
189 * The driver.owner field should be set to the module owner of this driver.
190 * The driver.name field should be set to the name of this driver (remember
191 * it will show up in sysfs, so it needs to be short and to the point.
192 * Useing the module name is a good idea.)
