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
