This patch includes 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 diffs are specific to the Linux 2.6.24-rc2 kernel
distribution.

This version reflects changes based on netdev list discussions
on 11/14/07 thru 11/15/07. It does away with in-the-kernel RS/RA
pinging and now asks that the task be performed by an application.
The application will essentially entail a port of the FreeBSD 'rtsold'
daemon, and will use the standard socket API.

I think we've made Fred jump through enough hoops :-)
I've added this to net-2.6.25, any fixups should be
sent relative to this, thanks.

Although that default router lookup on every packet doesn't
look so cheap, I wonder if there is a less expensive way to
implement that bit.
