At the same time we make the interaction between the socket and link layer simpler and more consistent. v2: - Simplified link congestion check to only check against own importance limit. This reduces the risk of higher levels starving out lower levels. v3: - Adding one sent message to to link backlog queue even if there is congestion, as suggested by Partha. - Allowing link_wakeup() loop to continue adding messages to the backlog queue even if one or more levels are congested. This seems to have a positive effect on performance. v4: - Added Partha's fixes, except for #4. I think having a multicast being blocked after unicast link congestion is an acceptable behavior when weighed against the risks of just purging the congestion list.
