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
