9.2.6 Indicating When to Start the Watchdog Routine
The following code shows how the
el_start_locked( )
routine indicates
the time for starting the driver’s
watchdog
interface. Although this task is
optional, we recommend that all network drivers perform this task.
ifp->if_timer = 3;
1
}
1
Sets the time (in seconds) for starting the
if_el
driver’s
watchdog( )
routine, called
el_watch( )
. After the transmit complete interrupt is
received, the interrupt service routine sets
if_timer
back to zero,
thereby disabling the
watchdog
timer.
