Description (partial)

Datapath for an FC port doesn't work and no frames will be sent out of the FC port - "sh int fc x/y | grep "frames output" wouldn't increment.  Shut/no-shut of the FC port wouldn't recover the problem state - FC link would come up successfully but data frames wouldn't be sent out of FC port.

The issue has been seen only when a corrupted SOP/EOP (Start of Packet/End of Packet) is received by the FC MAC in the FC MAC chip. So far, the issue has been very hard to reproduce.

This affects only the FC ports. Only the port hitting the issue is affected. If the port is in ethernet mode, the issue is not seen.
