Subject: [ANCP] Double tag in Access-Loop-Encapsulation TLV

Hi all,

When reading draft-ietf-ancp-protocol-12, I found Access-Loop-Encapsulation
supports only untagged Ethernet or single-tagged Ethernet encapsulation.
What about double-tagged ones?

Current definition comes from TR-101. However, as double-tagged interface is
common and useful for BNG to know, I suggest we add:

Byte 2: Encapsulation 1

         Double-tagged Ethernet = 3
