In BIRD, RX has lower priority than TX with the exception of RX from control socket. The patch replaces heuristic based on socket type with explicit mark and uses it for both control socket and BGP session waiting to be established. This should avoid an issue when during heavy load, outgoing connection could connect (TX event), send open, but then failed to receive OPEN / establish in time, not sending notifications between and therefore got hold timer expired error from the neighbor immediately after it finally established the connection.
