John Baldwin b1f459a01b Use a private callout timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.  The driver already contained an optional stats
timer that individual attachments could use to provide a 'tick' event.  The
stats timer only ran if the tick function pointer was non-NULL and the
attachment's tick routine had to call callout_reset(), etc.  Now the driver
always schedules a stat timer and manages the callout_reset() internally.
This timer is used to drive the watchdog and will also call the attachment's
'tick' handler if one is provided.
