Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * 
+ *  12/10/99 - Alpha Release 0.1.0
+ *            First release to the public
+ *  03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
+ *		malloc free checks, reviewed code. <alan@redhat.com>
+ *  03/13/00 - Added spinlocks for smp
+ *  03/08/01 - Added support for module_init() and module_exit()
+ *  08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
+ *             calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
+ *  11/05/01 - Restructured the interrupt function, added delays, reduced the 
+ *             the number of TX descriptors to 1, which together can prevent 
+ *             the card from locking up the box - <yoder1@us.ibm.com>
+ *  09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
+ *  11/13/02 - Removed free_irq calls which could cause a hang, added
+ *	       netif_carrier_{on|off} - <yoder1@us.ibm.com>
+ *  
+ *  To Do:
+ *
+ *
+ *  If Problems do Occur
+ *  Most problems can be rectified by either closing and opening the interface
+ *  (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
+ *  if compiled into the kernel).
