[j-nsp] encapsulation flexible-ethernet-services

[Patrik Olsson]

In short:

Flexible ethernet services allow for mixing Q and QinQ tagging and not  
using tags on different IFL:s on same physical interface. It also  
allows the usage of different encapsulations for different IFL:s on  
smae physical interface. Usable if you want to terminate L3VPN, L2VPN,  
nativew IP etc on different VLAN tags on same physical interface.

Cheers
Patrik
