You said it must call PortInterface::OnSentPacket, but then it doesn't.  I know
we don't care much about RelayPort, but at least you could put a comment about
this.

Done. To be honest, I'm not entirely sure how or if RelayPort is being used
today. I'm happy to do a follow-up if you have suggestions for improvements.
