  SVN rev 181298 on 2008-08-04 19:19:18Z by jhb
  
  Add locking to snc(4) so it is MPSAFE:
  - Add a mutex to the softc to protect the softc and device hardware.
  - Use a private timer routine to drive the transmit watchdog timer instead
    of using if_watchdog/if_timer.
  - If if_alloc() fails during attach, fail the attach with an error rather
    than panic'ing.
  - Clear RUNNING and OACTIVE only in sncstop().
  - Don't mess with IFF_UP.
  - Don't leak 'struct ifnet' on detach.
  - Setup interrupt handler after ether_ifattach().
  - Call ether_ifdetach() rather than if_detach() in the pccard detach
    routine.
