Subject: [PATCH 01/04] ipv6: RFC4214 Support (5)

From: Fred L. Templin <fred.l.templin@...ing.com>

This is experimental support for the Intra-Site Automatic
Tunnel Addressing Protocol (ISATAP) per RFC4214. It uses
the SIT module, and is configured using extensions to the
"iproute2" utility.

The following diffs are specific to the Linux 2.6.24-rc2
kernel distribution.
