Description (partial)

Symptom:
CRC errors and packet drop on traffic received from 100G F3 interface.

Conditions:
The issue happens when a packet is received on a trunk enabled interface (trunk port or Fabricpath port or layer 3 sub-interface) and has to exit on an interface with no tag.  Even if it arrives on the native vlan or main interface on the input interface without a tag it will still cause CRCs on the next hop device.
