Subject: [net-next PATCH RFC 0/3] Preserve skb->mark through VTI tunnels

These patches are meant to try and address the fact the VTI tunnels are
currently overwriting the skb->mark value.  I am generally happy with the
first two patches, however the third patch still modifies the skb->mark,
though it undoes after the fact.

The main problem I am trying to address is the fact that currently if I use
an v6 over v6 VTI tunnel I cannot receive any traffic on the interface as
the skb->mark is bleeding through and causing the traffic to be dropped.
