+
+GNU General Public License 
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.  
+59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to 
+share and change it. By contrast, the GNU General Public License is intended
+to guarantee your freedom to share and change free software--to make sure 
+the software is free for all its users. This General Public License applies 
+to most of the Free Software Foundation's software and to any other program 
+whose authors commit to using it. (Some other Free Software Foundation 
+software is covered by the GNU Library General Public License instead.) You 
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom 
+to distribute copies of free software (and charge for this service if you 
+wish), that you receive source code or can get it if you want it, that you 
+can change the software or use pieces of it in new free programs; and that 
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to 
+deny you these rights or to ask you to surrender the rights. These 
+restrictions translate to certain responsibilities for you if you distribute
+copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or 
+for a fee, you must give the recipients all the rights that you have. You 
+must make sure that they, too, receive or can get the source code. And you 
+must show them these terms so they know their rights.
+ 
+We protect your rights with two steps: (1) copyright the software, and (2) 
+offer you this license which gives you legal permission to copy, distribute 
+and/or modify the software. 
+
+Also, for each author's protection and ours, we want to make certain that 
+everyone understands that there is no warranty for this free software. If 
+the software is modified by someone else and passed on, we want its 
+recipients to know that what they have is not the original, so that any 
+problems introduced by others will not reflect on the original authors' 
+reputations. 
+
+Finally, any free program is threatened constantly by software patents. We 
+wish to avoid the danger that redistributors of a free program will 
+individually obtain patent licenses, in effect making the program 
+proprietary. To prevent this, we have made it clear that any patent must be 
+licensed for everyone's free use or not licensed at all. 
+
+The precise terms and conditions for copying, distribution and modification 
+follow. 
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+   placed by the copyright holder saying it may be distributed under the 
+   terms of this General Public License. The "Program", below, refers to any
+   such program or work, and a "work based on the Program" means either the 
+   Program or any derivative work under copyright law: that is to say, a 
+   work containing the Program or a portion of it, either verbatim or with 
+   modifications and/or translated into another language. (Hereinafter, 
+   translation is included without limitation in the term "modification".) 
+   Each licensee is addressed as "you". 
+
+   Activities other than copying, distribution and modification are not 
+   covered by this License; they are outside its scope. The act of running 
+   the Program is not restricted, and the output from the Program is covered 
+   only if its contents constitute a work based on the Program (independent 
+   of having been made by running the Program). Whether that is true depends
+   on what the Program does. 
+
+1. You may copy and distribute verbatim copies of the Program's source code 
+   as you receive it, in any medium, provided that you conspicuously and 
+   appropriately publish on each copy an appropriate copyright notice and 
+   disclaimer of warranty; keep intact all the notices that refer to this 
+   License and to the absence of any warranty; and give any other recipients 
+   of the Program a copy of this License along with the Program. 
+
+   You may charge a fee for the physical act of transferring a copy, and you 
+   may at your option offer warranty protection in exchange for a fee. 
+
+2. You may modify your copy or copies of the Program or any portion of it, 
+   thus forming a work based on the Program, and copy and distribute such 
+   modifications or work under the terms of Section 1 above, provided that 
+   you also meet all of these conditions: 
+
+   * a) You must cause the modified files to carry prominent notices stating 
+        that you changed the files and the date of any change. 
+
+   * b) You must cause any work that you distribute or publish, that in 
+        whole or in part contains or is derived from the Program or any part 
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the terms of this License. 
+
+   * c) If the modified program normally reads commands interactively when 
+        run, you must cause it, when started running for such interactive 
+        use in the most ordinary way, to print or display an announcement 
+        including an appropriate copyright notice and a notice that there is
+        no warranty (or else, saying that you provide a warranty) and that 
+        users may redistribute the program under these conditions, and 
+        telling the user how to view a copy of this License. (Exception: if 
+        the Program itself is interactive but does not normally print such 
+        an announcement, your work based on the Program is not required to 
+        print an announcement.) 
+
+   These requirements apply to the modified work as a whole. If identifiable 
+   sections of that work are not derived from the Program, and can be 
+   reasonably considered independent and separate works in themselves, then 
+   this License, and its terms, do not apply to those sections when you 
+   distribute them as separate works. But when you distribute the same 
+   sections as part of a whole which is a work based on the Program, the 
+   distribution of the whole must be on the terms of this License, whose 
+   permissions for other licensees extend to the entire whole, and thus to 
+   each and every part regardless of who wrote it. 
+
+   Thus, it is not the intent of this section to claim rights or contest 
+   your rights to work written entirely by you; rather, the intent is to 
+   exercise the right to control the distribution of derivative or 
+   collective works based on the Program. 
+
+   In addition, mere aggregation of another work not based on the Program 
+   with the Program (or with a work based on the Program) on a volume of a 
+   storage or distribution medium does not bring the other work under the 
+   scope of this License. 
+
+3. You may copy and distribute the Program (or a work based on it, under 
+   Section 2) in object code or executable form under the terms of Sections 
+   1 and 2 above provided that you also do one of the following: 
+
+   * a) Accompany it with the complete corresponding machine-readable source 
+        code, which must be distributed under the terms of Sections 1 and 2 
+        above on a medium customarily used for software interchange; or, 
+
+   * b) Accompany it with a written offer, valid for at least three years, 
+        to give any third party, for a charge no more than your cost of 
+        physically performing source distribution, a complete machine-
+        readable copy of the corresponding source code, to be distributed 
+        under the terms of Sections 1 and 2 above on a medium customarily 
+        used for software interchange; or, 
+
+   * c) Accompany it with the information you received as to the offer to 
+        distribute corresponding source code. (This alternative is allowed 
+        only for noncommercial distribution and only if you received the 
+        program in object code or executable form with such an offer, in 
+        accord with Subsection b above.) 
+
+   The source code for a work means the preferred form of the work for 
+   making modifications to it. For an executable work, complete source code 
+   means all the source code for all modules it contains, plus any 
+   associated interface definition files, plus the scripts used to control 
+   compilation and installation of the executable. However, as a special 
+   exception, the source code distributed need not include anything that is 
+   normally distributed (in either source or binary form) with the major 
+   components (compiler, kernel, and so on) of the operating system on which
+   the executable runs, unless that component itself accompanies the 
+   executable. 
+
+   If distribution of executable or object code is made by offering access 
+   to copy from a designated place, then offering equivalent access to copy 
+   the source code from the same place counts as distribution of the source 
+   code, even though third parties are not compelled to copy the source 
+   along with the object code. 
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+   expressly provided under this License. Any attempt otherwise to copy, 
+   modify, sublicense or distribute the Program is void, and will 
+   automatically terminate your rights under this License. However, parties 
+   who have received copies, or rights, from you under this License will not
+   have their licenses terminated so long as such parties remain in full 
+   compliance. 
+
+5. You are not required to accept this License, since you have not signed 
+   it. However, nothing else grants you permission to modify or distribute 
+   the Program or its derivative works. These actions are prohibited by law 
+   if you do not accept this License. Therefore, by modifying or 
+   distributing the Program (or any work based on the Program), you 
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Program or works 
+   based on it. 
+
+6. Each time you redistribute the Program (or any work based on the 
+   Program), the recipient automatically receives a license from the 
+   original licensor to copy, distribute or modify the Program subject to 
+   these terms and conditions. You may not impose any further restrictions 
+   on the recipients' exercise of the rights granted herein. You are not 
+   responsible for enforcing compliance by third parties to this License. 
+
+7. If, as a consequence of a court judgment or allegation of patent 
+   infringement or for any other reason (not limited to patent issues), 
+   conditions are imposed on you (whether by court order, agreement or 
+   otherwise) that contradict the conditions of this License, they do not 
+   excuse you from the conditions of this License. If you cannot distribute 
+   so as to satisfy simultaneously your obligations under this License and 
+   any other pertinent obligations, then as a consequence you may not 
+   distribute the Program at all. For example, if a patent license would 
+   not permit royalty-free redistribution of the Program by all those who 
+   receive copies directly or indirectly through you, then the only way you 
+   could satisfy both it and this License would be to refrain entirely from 
+   distribution of the Program. 
+
+   If any portion of this section is held invalid or unenforceable under any
+   particular circumstance, the balance of the section is intended to apply
+   and the section as a whole is intended to apply in other circumstances. 
+
+   It is not the purpose of this section to induce you to infringe any 
+   patents or other property right claims or to contest validity of any 
+   such claims; this section has the sole purpose of protecting the 
+   integrity of the free software distribution system, which is implemented 
+   by public license practices. Many people have made generous contributions
+   to the wide range of software distributed through that system in 
+   reliance on consistent application of that system; it is up to the 
+   author/donor to decide if he or she is willing to distribute software 
+   through any other system and a licensee cannot impose that choice. 
+
+   This section is intended to make thoroughly clear what is believed to be 
+   a consequence of the rest of this License. 
+
+8. If the distribution and/or use of the Program is restricted in certain 
+   countries either by patents or by copyrighted interfaces, the original 
+   copyright holder who places the Program under this License may add an 
+   explicit geographical distribution limitation excluding those countries, 
+   so that distribution is permitted only in or among countries not thus 
+   excluded. In such case, this License incorporates the limitation as if 
+   written in the body of this License. 
+
+9. The Free Software Foundation may publish revised and/or new versions of 
+   the General Public License from time to time. Such new versions will be 
+   similar in spirit to the present version, but may differ in detail to 
+   address new problems or concerns. 
+
+   Each version is given a distinguishing version number. If the Program 
+   specifies a version number of this License which applies to it and "any 
+   later version", you have the option of following the terms and 
+   conditions either of that version or of any later version published by 
+   the Free Software Foundation. If the Program does not specify a version 
+   number of this License, you may choose any version ever published by the 
+   Free Software Foundation. 
+
+10. If you wish to incorporate parts of the Program into other free programs
+    whose distribution conditions are different, write to the author to ask 
+    for permission. For software which is copyrighted by the Free Software 
+    Foundation, write to the Free Software Foundation; we sometimes make 
+    exceptions for this. Our decision will be guided by the two goals of 
+    preserving the free status of all derivatives of our free software and 
+    of promoting the sharing and reuse of software generally. 
+
+   NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
+    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
+    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
+    NECESSARY SERVICING, REPAIR OR CORRECTION. 
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
+    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest 
+possible use to the public, the best way to achieve this is to make it free 
+software which everyone can redistribute and change under these terms. 
+
+To do so, attach the following notices to the program. It is safest to 
+attach them to the start of each source file to most effectively convey the
+exclusion of warranty; and each file should have at least the "copyright" 
+line and a pointer to where the full notice is found. 
+
+one line to give the program's name and an idea of what it does.
+Copyright (C) yyyy  name of author
+
+This program is free software; you can redistribute it and/or modify it 
+under the terms of the GNU General Public License as published by the Free 
+Software Foundation; either version 2 of the License, or (at your option) 
+any later version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT 
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or 
+FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for 
+more details.
+
+You should have received a copy of the GNU General Public License along with
+this program; if not, write to the Free Software Foundation, Inc., 59 
+Temple Place - Suite 330, Boston, MA  02111-1307, USA.
+
+Also add information on how to contact you by electronic and paper mail. 
+
+If the program is interactive, make it output a short notice like this when 
+it starts in an interactive mode: 
+
+Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 
+with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free 
+software, and you are welcome to redistribute it under certain conditions; 
+type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate 
+parts of the General Public License. Of course, the commands you use may be 
+called something other than 'show w' and 'show c'; they could even be 
+mouse-clicks or menu items--whatever suits your program. 
+
+You should also get your employer (if you work as a programmer) or your 
+school, if any, to sign a "copyright disclaimer" for the program, if 
+necessary. Here is a sample; alter the names: 
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
+'Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into 
+proprietary programs. If your program is a subroutine library, you may 
+consider it more useful to permit linking proprietary applications with the 
+library. If this is what you want to do, use the GNU Library General Public 
+License instead of this License.

+/* Change Log
+ * 5.3.12	6/7/04
+ * - kcompat NETIF_MSG for older kernels (2.4.9) <sean.p.mcdermott@intel.com>
+ * - if_mii support and associated kcompat for older kernels
+ * - More errlogging support from Jon Mason <jonmason@us.ibm.com>
+ * - Fix TSO issues on PPC64 machines -- Jon Mason <jonmason@us.ibm.com>
+ *
+ * 5.7.1	12/16/04
+ * - Resurrect 82547EI/GI related fix in e1000_intr to avoid deadlocks. This
+ *   fix was removed as it caused system instability. The suspected cause of 
+ *   this is the called to e1000_irq_disable in e1000_intr. Inlined the 
+ *   required piece of e1000_irq_disable into e1000_intr - Anton Blanchard
+ * 5.7.0	12/10/04
+ * - include fix to the condition that determines when to quit NAPI - Robert Olsson
+ * - use netif_poll_{disable/enable} to synchronize between NAPI and i/f up/down
+ * 5.6.5 	11/01/04
+ * - Enabling NETIF_F_SG without checksum offload is illegal - 
+     John Mason <jdmason@us.ibm.com>
+ * 5.6.3        10/26/04
+ * - Remove redundant initialization - Jamal Hadi
+ * - Reset buffer_info->dma in tx resource cleanup logic
+ * 5.6.2	10/12/04
+ * - Avoid filling tx_ring completely - shemminger@osdl.org
+ * - Replace schedule_timeout() with msleep()/msleep_interruptible() -
+ *   nacc@us.ibm.com
+ * - Sparse cleanup - shemminger@osdl.org
+ * - Fix tx resource cleanup logic
+ * - LLTX support - ak@suse.de and hadi@cyberus.ca
