from the softc.
- Rework the watchdog timer to match other NIC drivers:
- Start a timer in fe_init() that runs once a second and checks a counter
in the softc that is identical to the deprecated 'if_timer'.
- Just adjust the softc tx timeout value when sending packets instead of
scheduling the timer.
- Use IFQ_SET_MAXLEN().
