  Log:
  SVN rev 223198 on 2011-06-17 20:06:52Z by jhb
  
  - Use a dedicated task to handle deferred transmits from the if_transmit
    method instead of reusing the existing per-queue interrupt task.
    Reusing the per-queue interrupt task could result in both an interrupt
    thread and the taskqueue thread trying to handle received packets on a
    single queue resulting in out-of-order packet processing.
  - Don't define igb_start() at all on 8.0 and where if_transmit is used.
    Replace last remaining call to igb_start() with a loop to kick off
    transmit on each queue instead.
  - Call ether_ifdetach() earlier in igb_detach().
  - Drain tasks and free taskqueues during igb_detach().
