Description (partial)

Any Transport over MPLS (AToM) xconnects may fail to clear a dataplane
fault state, and never successfully re-establishes the dataplane and instead
just withdraws the label.  This can be seen in the following debug output:

Jun  5 18:57:03.829: AToM MGR [, 1]: ....... PW status TLV NOT enabled and
Jun  5 18:57:03.829: AToM MGR [, 1]: .......  our local AC is DOWN=>withdraw label

Jun  5 18:57:03.833: AToM MGR [, 1]: . Not activating dataplane: VC in remote ready state on Active RP

This symptom has been observed when the remote peer does not support the
pseudowire status TLV and does not readvertise its label when the faults
are cleared.
