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 includes the diff for ./include/linux/if.h which was missing in the v2.4 submission and is needed to make the patch compile. The patch has been installed, compiled and tested in a clean 2.6.24-rc2 kernel build area. Signed-off-by: Fred L.
