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!

+ * INET An implementation of the TCP/IP protocol suite for the LINUX
+ * operating system. INET is implemented using the BSD Socket
+ * interface as the means of communication with the user level.
+ *
+ * Definitions for the IP router.
+ *
+ * Version: @(#)route.h 1.0.4 05/27/93
+ *
+ * Authors: Ross Biro, <bir7@leland.Stanford.Edu>
+ * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
+ * Fixes:
+ * Alan Cox : Reformatted. Added ip_rt_local()
+ * Alan Cox : Support for TCP parameters.
+ * Alexey Kuznetsov: Major changes for new routing code.
+ * Mike McLagan : Routing by source
+ * Robert Olsson : Added rt_cache statistics
