The reason you need to make sure that you end up with hashes for both
src,dst and dst,src being equivalent is to ensure that when you create
an outbound socket, you know up front which path the receive path is
going to come back on. Right now we don't mark new connections -
inbound or outbound - with a flowid until we've received some data on
it.

It's also going to be eventually useful for the pcbgroup stuff, as
vijay has said.
