[j-nsp] encapsulation flexible-ethernet-services

[Chris Spears]

Flexible-vlan-tagging allows for mixing dot1q and QinQ tagging between 
logical units, not flexible-ethernet-services.

As they do different things, both can be applied on the same interface, 
and even used on the same logical unit.  For example, terminating a 
l2circuit into a switch with stacked tags, right alongside singly-tagged 
units.
