C6K, SUP720 (mix of 3B, 3BXL, 3C, 3CXL), running 15.1SY.

We have enabled uRPF with ACL exceptions to support DHCP relay (plus mls ip
cef rpf hw-enable-rpf-acl). This works as expected.

If we enable CoPP, the ACL exceptions for uRPF stop working. I can't find a
good explanation for this, and TAC isn't very helpful on the subject.

Anyone run into this?
