Linux-2.6.12-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!

+* 'dlci_intr_mode_unbusy' to 'sdla_t'
+* Oct 18, 1997 Jaspreet Singh Added structure to maintain global driver
+* statistics.
+* Jan 15, 1997 Gene Kozin Version 3.1.0
+* o added UDP management stuff
+* Jan 02, 1997 Gene Kozin Version 3.0.0
