Description (partial)

Symptom:
On a Cisco ASR9000-series -TR or -SE linecard, or ASR9001, an ipv4 or ipv6 access-list applied
on an egress L3 interface causes all outgoing MPLS->IP traffic for that interface to be dropped.

Conditions:
All MPLS->IP traffic is dropped by the egress access-list, where the disposition is done by a
per-prefix or per-CE disposition label. Packets destined to a per-vrf (aka "deagg") disposition label are not affected.
