[j-nsp] Stiching L2 to L3 on MX480

[adamv0025 at netconsultings.com]

Hi Aaron,

In Carrier Ethernet VLAN IDs are arbitrary at both ends of the PW.
In other words, you can do whatever you want at each end pop/push/translate
one/two VLAN headers (QinQ or 802.1ad). 
The only thing that both ends need to agree on with regards to VLAN tagging
is the resulting MTU.
