{}s please

[pthatcher1, 2015/10/05 18:30:14]

Do we really need to know which connection it went out on?  Can we just put
OnPacketSent on the Port and avoid doing a map lookup for every packet?

I think this is a good idea, now that I begin understand how these things are
connected. :)

Just to be sure, you are saying I should send a signal from Port(Interface) via
P2PTransportChannel and from there up to webrtc?

[pthatcher1, 2015/10/06 20:23:55]

Yes.

[stefan-webrtc, 2015/10/07 16:55:25]

Done.
