4.6 STETHER_InterruptHandler ()
Prototype:
void STETHER_InterruptHandler(NGifnet * netp)
Description:
This function is the interrupt handler wrapper. It handles TX, RX and error interrupts derived from
tscIsr()
and tscDpr(). The function begins by isolating the interrupt source and then clearing the
interrupt(s). If statistics are being collected, it updates the interrupt related portion. Based on its
interrogation of the interrupt source, it may call STETHER_HandleCompletedTxBuffers.
Parameters:
netp network interface type NGethifnet_tsc
Returns:
none
