mpls: no per-MPLS-tunnel tx node
Type: improvement do not add a per-MPLS tunnel tx node. per-tunnl nodes limit the number of tunnels that can be created to the number o fnodes that can be created (64k). improve the tx node. Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I6016f05e809c6c64a0b098a101b28c9dd47824b3
