a) macro-ization of all mbuf and random number
access plus timers. This makes the code more portable and able to change out the mbuf or timer system used more easily ;-) b) removal of all use of pkt-hdr's until only the places we need them (before ip_output routines). c) remove a bunch of code not needed due to <b> aka worrying about pkthdr's :-) d) There was one last reorder problem it looks where if a restart occur's and we release and relock (at the point where we setup our alias vtag) we would end up possibly getting the wrong TSN in place. The code that fixed the TSN's just needed to be shifted around BEFORE the release of the lock.. also code that set the state (since this also could contribute). Approved by: gnn
