Sorry to keep doing this but I realized that there is some more code
that we can delete:
 * We can dump all the protocol related header includes in tunnel.c.
Normally, I wouldn't really care but there's a lot of unrelated stuff
 * Since this deletes any semblance of multicast support from the
kernel, we can do the equivalent from userspace as well.  This is
really just ofproto/tunnel.c:tnl_find() and blocking the addition of
multicast remote IPs in netdev-vport.c.
 * We can also remove the VXLAN bullet from the top of
ofproto/tunnel.c since that should work now and also multicast group
management since that's covered by the point above.
 * I noticed that there's also some remnant of patch ports in
include/linux/openvswitch.h that we can remove (this is probably a
separate patch).

This will be really great once all the old code is gone.
