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!

+ * 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 protocol dispatcher.
+ *
+ * Version:     @(#)protocol.h  1.0.2   05/07/93
+ *
+ * Author:      Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>

+ *
+ *      Changes:
+ *              Alan Cox        :       Added a name field and a frag handler
+ *                                      field for later.
+ *              Alan Cox        :       Cleaned up, and sorted types.
+ *              Pedro Roque     :       inet6 protocols
