Description (partial)

Symptom:
During boot after NX-OS downgrade 6.2(10) -> 6.2(2a), "flowcontrol receive on" and "flowcontrol send on" is not set on physical interface.
These configurations on port-channel interface is set without problem.
Therefore physical interface cannot join port-channel for configuration differential.
