Your original patch had issues with looping of traffic and this patch also
has still some
other issues imported from your original implementation.

If i would write it from scratch it would been more similar to gif/gre
rather than this one.
The target was to have it operational.

If you feel that you will finish rather soon your implementation than ok
for postponing.
If you think its better to put this in and than you can push yours even
better.

Whichever is faster/better.
