> The changes are as follows:
> 1. Teach tunnel4.c about AF_MPLS, it already understands AF_INET and
>    AF_INET6
> 2. Enhance IPIP and SIT to handle MPLS. Both already handle IPv4.
>    SIT also already handles IPv6.
> 3. Trivially enhance MPLS to allow routes over SIT and IPIP tunnels.

> A corresponding iproute2 patchset will also be posted.
