[j-nsp] MX204 Tunnel Services

[Fraser McGlinn]

Further to this, and to clarify I do already have tunnel-services enabled and after configuring I get output packets on each unit, but no input packets. It seems like the PFE is just eating the packets.

Interfaces are created and bandwidth set after enabling tunnel services on the PIC, however only output packets on the source interface increment. Input packets do not increment on the receiving unit, so seems to get lost in the nether.
