SVN rev 221690 on 2011-05-09 07:37:47Z by mav
Refactor TCP ISN increment logic. Instead of firing callout at 100Hz to
keep constant ISN growth rate, do the same directly inside tcp_new_isn(),
taking into account how much time (ticks) passed since the last call.
On my test systems this decreases idle interrupt rate from 140Hz to 70Hz.
