19 This routine is registered via the request_irq kernel API call, and
20 handles all interrupts generated from a specific MPT adapter (also
21 referred to as a IO Controller or IOC). This routine must clear the
22 interrupt from the adapter and does so by reading the reply FIFO.
23 Multiple replies may be processed per single call to this routine.
24
25 This routine handles register-level access of the adapter but
26 dispatches (calls) a protocol-specific callback routine to handle the
27 protocol-specific details of the MPT request completion.
