Good catch.
At one time I thought that this was necessary because IPv6 link-local addresses
are not necessarily unique to the node. So, you might need to probe by IP
address and something else (e.g., ifName). However, ifName is unique to the
node. So, one instance of the interface identification object is enough.
I will remove that sentence.

Fair enough. I will make that change in the next version.

Looking back, I described that badly. This bit is set if the interface is a
pseudowire endpoint and it is running Ethernet.
Maybe I should call it the P-bit for Pseudowire endpoint. We don't need to
specify what type of pseudowire it is.
What do you think?

[RB ]
Fair enough. I can make that change in the next revision.

Fair enough. I can make that change in the next revision.
