I think asymmetric configurations are fine, in particular
receive-only. I was reluctant to the send-only scenario initially
as I would expect a VTEP sending RCO frames on UDP dport 8472 to
also always be able to accept RCO frames on that port. I can't
come up with any specific cases where this would lead to problems
though so I have no objections.
As for GBP, as processing of the policy group requires additional
iptables or OVS rules anyway, such behaviour would be implemented
in those rules by either ignoring the mark or dropping such frames.
