[c-nsp] ASR 901 EoMPLS

Before XE 3.11 (15.3.4S) the behavior is:

1)      On EVC-BD, if no L2CP configuration is done, then tagged BPDUs are
dropped and untagged BPDUs are peered

2)      On EVC-Xconnect, by default, the tagged BPDUs are dropped and
untagged BPDUs are forwarded

3)      On Port-Xconnect, the tagged BPDUs are dropped and untagged BPDUs
are forwarded


This is not documented clearly and I'll work to get the external
documentation updated to reflect this and create a longer term goal to more
clearly state the behavior of control traffic on xconnect ports in
different configurations on different platforms.
