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!

+   buffer memory space.  NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of

+
+   Reading the SAPROM from a word-wide card with the 8390 set in byte-wide

+

+
+   We use the minimum memory size for some ethercard product lines, iff we can't
+   distinguish models.  You can increase the packet buffer size by setting
+   PACKETBUF_MEMSIZE.  Reported Cabletron packet buffer locations are:
+        E1010   starts at 0x100 and ends at 0x2000.
+        E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
