Description (partial)

Symptom:
When Tomahawk node works as MPLS-TP end node,  "show mpls forwarding" counter doesn't increase on tunnel-tp Aggregate entry,  the problem only happens to TP-OAM/TP label BFD packets (or any packet with GL label).   Real traffic over TP Tunnel can see counter increasing.
