[c-nsp] ASR9K bundle-id 123 mode on

[adam vitkovsky]

Oooh yes you're right I totally forgot about that, right the standby ASR9K
has to keep the port on dual homed device in check
Though that can be done either via LACP priority change or via "Brute-force"
-meaning the standby ASR9K will shut-down the standby port -I'll try the
second mode of operation to see whether I can trick this

The ports belonging to a mLACP bundle have to be running LACP.  The
non-forwarding ASR9K uses LACP to keep the peer port in a standby state.
Putting the port in loopback would mean it would have to run LACP with
itself somehow, not sure if that's going to work... You could probably use a
loopback cable to another port on the same node in a different bundle.
