- 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. Tested by: no one despite repeated requests
