35 | |||
36 | Copyright (C) 1989, 1991 Free Software Foundation, Inc. | ||
37 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA | ||
38 | Everyone is permitted to copy and distribute verbatim copies | ||
39 | of this license document, but changing it is not allowed. | ||
40 | |||
41 | Preamble | ||
42 | |||
43 | The licenses for most software are designed to take away your | ||
44 | freedom to share and change it. By contrast, the GNU General Public | ||
45 | License is intended to guarantee your freedom to share and change free | ||
46 | software--to make sure the software is free for all its users. This | ||
47 | General Public License applies to most of the Free Software | ||
48 | Foundation's software and to any other program whose authors commit to | ||
49 | using it. (Some other Free Software Foundation software is covered by | ||
50 | the GNU Lesser General Public License instead.) You can apply it to | ||
51 | your programs, too. | ||
52 | |||
53 | When we speak of free software, we are referring to freedom, not | ||
54 | price. Our General Public Licenses are designed to make sure that you | ||
55 | have the freedom to distribute copies of free software (and charge for | ||
56 | this service if you wish), that you receive source code or can get it | ||
57 | if you want it, that you can change the software or use pieces of it | ||
58 | in new free programs; and that you know you can do these things. | ||
59 | |||
60 | To protect your rights, we need to make restrictions that forbid | ||
61 | anyone to deny you these rights or to ask you to surrender the rights. | ||
62 | These restrictions translate to certain responsibilities for you if you | ||
63 | distribute copies of the software, or if you modify it. | ||
64 | |||
65 | For example, if you distribute copies of such a program, whether | ||
66 | gratis or for a fee, you must give the recipients all the rights that | ||
67 | you have. You must make sure that they, too, receive or can get the | ||
68 | source code. And you must show them these terms so they know their | ||
69 | rights. | ||
70 | |||
71 | We protect your rights with two steps: (1) copyright the software, and | ||
72 | (2) offer you this license which gives you legal permission to copy, | ||
73 | distribute and/or modify the software. | ||
74 | |||
75 | Also, for each author's protection and ours, we want to make certain | ||
76 | that everyone understands that there is no warranty for this free | ||
77 | software. If the software is modified by someone else and passed on, we | ||
78 | want its recipients to know that what they have is not the original, so | ||
79 | that any problems introduced by others will not reflect on the original | ||
80 | authors' reputations. | ||
81 | |||
82 | Finally, any free program is threatened constantly by software | ||
83 | patents. We wish to avoid the danger that redistributors of a free | ||
84 | program will individually obtain patent licenses, in effect making the | ||
85 | program proprietary. To prevent this, we have made it clear that any | ||
86 | patent must be licensed for everyone's free use or not licensed at all. | ||
87 | |||
88 | The precise terms and conditions for copying, distribution and | ||
89 | modification follow. | ||
90 | |||
91 | GNU GENERAL PUBLIC LICENSE | ||
92 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | ||
93 | |||
94 | 0. This License applies to any program or other work which contains | ||
95 | a notice placed by the copyright holder saying it may be distributed | ||
96 | under the terms of this General Public License. The "Program", below, | ||
97 | refers to any such program or work, and a "work based on the Program" | ||
98 | means either the Program or any derivative work under copyright law: | ||
99 | that is to say, a work containing the Program or a portion of it, | ||
100 | either verbatim or with modifications and/or translated into another | ||
101 | language. (Hereinafter, translation is included without limitation in | ||
102 | the term "modification".) Each licensee is addressed as "you". | ||
103 | |||
104 | Activities other than copying, distribution and modification are not | ||
105 | covered by this License; they are outside its scope. The act of | ||
106 | running the Program is not restricted, and the output from the Program | ||
107 | is covered only if its contents constitute a work based on the | ||
108 | Program (independent of having been made by running the Program). | ||
109 | Whether that is true depends on what the Program does. | ||
110 | |||
111 | 1. You may copy and distribute verbatim copies of the Program's | ||
112 | source code as you receive it, in any medium, provided that you | ||
113 | conspicuously and appropriately publish on each copy an appropriate | ||
114 | copyright notice and disclaimer of warranty; keep intact all the | ||
115 | notices that refer to this License and to the absence of any warranty; | ||
116 | and give any other recipients of the Program a copy of this License | ||
117 | along with the Program. | ||
118 | |||
119 | You may charge a fee for the physical act of transferring a copy, and | ||
120 | you may at your option offer warranty protection in exchange for a fee. | ||
121 | |||
122 | 2. You may modify your copy or copies of the Program or any portion | ||
123 | of it, thus forming a work based on the Program, and copy and | ||
124 | distribute such modifications or work under the terms of Section 1 | ||
125 | above, provided that you also meet all of these conditions: | ||
126 | |||
127 | a) You must cause the modified files to carry prominent notices | ||
128 | stating that you changed the files and the date of any change. | ||
129 | |||
130 | b) You must cause any work that you distribute or publish, that in | ||
131 | whole or in part contains or is derived from the Program or any | ||
132 | part thereof, to be licensed as a whole at no charge to all third | ||
133 | parties under the terms of this License. | ||
134 | |||
135 | c) If the modified program normally reads commands interactively | ||
136 | when run, you must cause it, when started running for such | ||
137 | interactive use in the most ordinary way, to print or display an | ||
138 | announcement including an appropriate copyright notice and a | ||
139 | notice that there is no warranty (or else, saying that you provide | ||
140 | a warranty) and that users may redistribute the program under | ||
141 | these conditions, and telling the user how to view a copy of this | ||
142 | License. (Exception: if the Program itself is interactive but | ||
143 | does not normally print such an announcement, your work based on | ||
144 | the Program is not required to print an announcement.) | ||
145 | |||
146 | These requirements apply to the modified work as a whole. If | ||
147 | identifiable sections of that work are not derived from the Program, | ||
148 | and can be reasonably considered independent and separate works in | ||
149 | themselves, then this License, and its terms, do not apply to those | ||
150 | sections when you distribute them as separate works. But when you | ||
151 | distribute the same sections as part of a whole which is a work based | ||
152 | on the Program, the distribution of the whole must be on the terms of | ||
153 | this License, whose permissions for other licensees extend to the | ||
154 | entire whole, and thus to each and every part regardless of who wrote it. | ||
155 | |||
156 | Thus, it is not the intent of this section to claim rights or contest | ||
157 | your rights to work written entirely by you; rather, the intent is to | ||
158 | exercise the right to control the distribution of derivative or | ||
159 | collective works based on the Program. | ||
160 | |||
161 | In addition, mere aggregation of another work not based on the Program | ||
162 | with the Program (or with a work based on the Program) on a volume of | ||
163 | a storage or distribution medium does not bring the other work under | ||
164 | the scope of this License. | ||
165 | |||
166 | 3. You may copy and distribute the Program (or a work based on it, | ||
167 | under Section 2) in object code or executable form under the terms of | ||
168 | Sections 1 and 2 above provided that you also do one of the following: | ||
169 | |||
170 | a) Accompany it with the complete corresponding machine-readable | ||
171 | source code, which must be distributed under the terms of Sections | ||
172 | 1 and 2 above on a medium customarily used for software interchange; or, | ||
173 | |||
174 | b) Accompany it with a written offer, valid for at least three | ||
175 | years, to give any third party, for a charge no more than your | ||
176 | cost of physically performing source distribution, a complete | ||
177 | machine-readable copy of the corresponding source code, to be | ||
178 | distributed under the terms of Sections 1 and 2 above on a medium | ||
179 | customarily used for software interchange; or, | ||
180 | |||
181 | c) Accompany it with the information you received as to the offer | ||
182 | to distribute corresponding source code. (This alternative is | ||
183 | allowed only for noncommercial distribution and only if you | ||
184 | received the program in object code or executable form with such | ||
185 | an offer, in accord with Subsection b above.) | ||
186 | |||
187 | The source code for a work means the preferred form of the work for | ||
188 | making modifications to it. For an executable work, complete source | ||
189 | code means all the source code for all modules it contains, plus any | ||
190 | associated interface definition files, plus the scripts used to | ||
191 | control compilation and installation of the executable. However, as a | ||
192 | special exception, the source code distributed need not include | ||
193 | anything that is normally distributed (in either source or binary | ||
194 | form) with the major components (compiler, kernel, and so on) of the | ||
195 | operating system on which the executable runs, unless that component | ||
196 | itself accompanies the executable. | ||
197 | |||
198 | If distribution of executable or object code is made by offering | ||
199 | access to copy from a designated place, then offering equivalent | ||
200 | access to copy the source code from the same place counts as | ||
201 | distribution of the source code, even though third parties are not | ||
202 | compelled to copy the source along with the object code. | ||
203 | |||
204 | 4. You may not copy, modify, sublicense, or distribute the Program | ||
205 | except as expressly provided under this License. Any attempt | ||
206 | otherwise to copy, modify, sublicense or distribute the Program is | ||
207 | void, and will automatically terminate your rights under this License. | ||
208 | However, parties who have received copies, or rights, from you under | ||
209 | this License will not have their licenses terminated so long as such | ||
210 | parties remain in full compliance. | ||
211 | |||
212 | 5. You are not required to accept this License, since you have not | ||
213 | signed it. However, nothing else grants you permission to modify or | ||
214 | distribute the Program or its derivative works. These actions are | ||
215 | prohibited by law if you do not accept this License. Therefore, by | ||
216 | modifying or distributing the Program (or any work based on the | ||
217 | Program), you indicate your acceptance of this License to do so, and | ||
218 | all its terms and conditions for copying, distributing or modifying | ||
219 | the Program or works based on it. | ||
220 | |||
221 | 6. Each time you redistribute the Program (or any work based on the | ||
222 | Program), the recipient automatically receives a license from the | ||
223 | original licensor to copy, distribute or modify the Program subject to | ||
224 | these terms and conditions. You may not impose any further | ||
225 | restrictions on the recipients' exercise of the rights granted herein. | ||
226 | You are not responsible for enforcing compliance by third parties to | ||
227 | this License. | ||
228 | |||
229 | 7. If, as a consequence of a court judgment or allegation of patent | ||
230 | infringement or for any other reason (not limited to patent issues), | ||
231 | conditions are imposed on you (whether by court order, agreement or | ||
232 | otherwise) that contradict the conditions of this License, they do not | ||
233 | excuse you from the conditions of this License. If you cannot | ||
234 | distribute so as to satisfy simultaneously your obligations under this | ||
235 | License and any other pertinent obligations, then as a consequence you | ||
236 | may not distribute the Program at all. For example, if a patent | ||
237 | license would not permit royalty-free redistribution of the Program by | ||
238 | all those who receive copies directly or indirectly through you, then | ||
239 | the only way you could satisfy both it and this License would be to | ||
240 | refrain entirely from distribution of the Program. | ||
241 | |||
242 | If any portion of this section is held invalid or unenforceable under | ||
243 | any particular circumstance, the balance of the section is intended to | ||
244 | apply and the section as a whole is intended to apply in other | ||
245 | circumstances. | ||
246 | |||
247 | It is not the purpose of this section to induce you to infringe any | ||
248 | patents or other property right claims or to contest validity of any | ||
249 | such claims; this section has the sole purpose of protecting the | ||
250 | integrity of the free software distribution system, which is | ||
251 | implemented by public license practices. Many people have made | ||
252 | generous contributions to the wide range of software distributed | ||
253 | through that system in reliance on consistent application of that | ||
254 | system; it is up to the author/donor to decide if he or she is willing | ||
255 | to distribute software through any other system and a licensee cannot | ||
256 | impose that choice. | ||
257 | |||
258 | This section is intended to make thoroughly clear what is believed to | ||
259 | be a consequence of the rest of this License. | ||
260 | |||
261 | 8. If the distribution and/or use of the Program is restricted in | ||
262 | certain countries either by patents or by copyrighted interfaces, the | ||
263 | original copyright holder who places the Program under this License | ||
264 | may add an explicit geographical distribution limitation excluding | ||
265 | those countries, so that distribution is permitted only in or among | ||
266 | countries not thus excluded. In such case, this License incorporates | ||
267 | the limitation as if written in the body of this License. | ||
268 | |||
269 | 9. The Free Software Foundation may publish revised and/or new versions | ||
270 | of the General Public License from time to time. Such new versions will | ||
271 | be similar in spirit to the present version, but may differ in detail to | ||
272 | address new problems or concerns. | ||
273 | |||
274 | Each version is given a distinguishing version number. If the Program | ||
275 | specifies a version number of this License which applies to it and "any | ||
276 | later version", you have the option of following the terms and conditions | ||
277 | either of that version or of any later version published by the Free | ||
278 | Software Foundation. If the Program does not specify a version number of | ||
279 | this License, you may choose any version ever published by the Free Software | ||
280 | Foundation. | ||
281 | |||
282 | 10. If you wish to incorporate parts of the Program into other free | ||
283 | programs whose distribution conditions are different, write to the author | ||
284 | to ask for permission. For software which is copyrighted by the Free | ||
285 | Software Foundation, write to the Free Software Foundation; we sometimes | ||
286 | make exceptions for this. Our decision will be guided by the two goals | ||
287 | of preserving the free status of all derivatives of our free software and | ||
288 | of promoting the sharing and reuse of software generally. | ||
289 | |||
290 | NO WARRANTY | ||
291 | |||
292 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | ||
293 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | ||
294 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | ||
295 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | ||
296 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | ||
297 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | ||
298 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | ||
299 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | ||
300 | REPAIR OR CORRECTION. | ||
301 | |||
302 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | ||
303 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | ||
304 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | ||
305 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | ||
306 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | ||
307 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | ||
308 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | ||
309 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | ||
310 | POSSIBILITY OF SUCH DAMAGES. | ||

1 | Operating FCoE using bnx2fc | ||
2 | =========================== | ||
3 | Broadcom FCoE offload through bnx2fc is full stateful hardware offload that | ||
4 | cooperates with all interfaces provided by the Linux ecosystem for FC/FCoE and | ||
5 | SCSI controllers. As such, FCoE functionality, once enabled is largely | ||
6 | transparent. Devices discovered on the SAN will be registered and unregistered | ||
7 | automatically with the upper storage layers. | ||
8 | |||
9 | Despite the fact that the Broadcom's FCoE offload is fully offloaded, it does | ||
10 | depend on the state of the network interfaces to operate. As such, the network | ||
11 | interface (e.g. eth0) associated with the FCoE offload initiator must be 'up'. | ||
12 | It is recommended that the network interfaces be configured to be brought up | ||
13 | automatically at boot time. | ||
14 | |||
15 | Furthermore, the Broadcom FCoE offload solution creates VLAN interfaces to | ||
16 | support the VLANs that have been discovered for FCoE operation (e.g. | ||
17 | eth0.1001-fcoe). Do not delete or disable these interfaces or FCoE operation | ||
18 | will be disrupted. | ||
19 | |||
20 | Driver Usage Model: | ||
21 | =================== | ||
22 | |||
23 | 1. Ensure that fcoe-utils package is installed. | ||
24 | |||
25 | 2. Configure the interfaces on which bnx2fc driver has to operate on. | ||
26 | Here are the steps to configure: | ||
27 | a. cd /etc/fcoe | ||
28 | b. copy cfg-ethx to cfg-eth5 if FCoE has to be enabled on eth5. | ||
29 | c. Repeat this for all the interfaces where FCoE has to be enabled. | ||
30 | d. Edit all the cfg-eth files to set "no" for DCB_REQUIRED** field, and | ||
31 | "yes" for AUTO_VLAN. | ||
32 | e. Other configuration parameters should be left as default | ||
33 | |||
34 | 3. Ensure that "bnx2fc" is in SUPPORTED_DRIVERS list in /etc/fcoe/config. | ||

36 | 4. Start fcoe service. (service fcoe start). If Broadcom devices are present in | ||
37 | the system, bnx2fc driver would automatically claim the interfaces, starts vlan | ||
38 | discovery and log into the targets. | ||
39 | |||
40 | 5. "Symbolic Name" in 'fcoeadm -i' output would display if bnx2fc has claimed | ||
41 | the interface. | ||
42 | Eg: | ||
43 | [root@bh2 ~]# fcoeadm -i | ||

68 | NOTE: | ||
69 | ==== | ||
70 | ** Broadcom FCoE capable devices implement a DCBX/LLDP client on-chip. Only one | ||
71 | LLDP client is allowed per interface. For proper operation all host software | ||
72 | based DCBX/LLDP clients (e.g. lldpad) must be disabled. To disable lldpad on a | ||
73 | given interface, run the following command: | ||
74 | |||
75 | lldptool set-lldp -i <interface_name> adminStatus=disabled | ||
