Abstract:
|
|
|
|
The main header for an Novell 2000 Miniport driver.
|
|

|
Author:

Sean Selitrennikoff
|
|
|
|
Environment:
|
|
|
|
Architecturally, there is an assumption in this driver that we are
|
|
on a little endian machine.

Routine Description:
|
|
|
|
Determines the type of the interrupt on the card. The order of
|
|
importance is overflow, then transmit complete, then receive.
|
|
Counter MSB is handled first since it is simple.
|
|
|
|
Arguments:
|
|
|
|
Adapter - pointer to the adapter block
|
|
|
|
InterruptStatus - Current Interrupt Status.
|
|
|
|
Return Value:
|
|
|
|
The type of the interrupt
