[S2IO]: Handle and monitor all of the device errors and alarms
- Added support to poll entire set of device errors and alarams.
- A note on how device errors and alarms are handled:
- The adapter will automatically recover from uncorrectable ECC errors.
Packets containing corrupted data will be dropped (not transmitted) or tagged
as invalid before being passed to the host.
- The adapter cannot recover from any internal state machine errors. A state
machine error requires a device reset.
- Any internal error that could potentially result in .store trampling.
(undesirable PCI behaviour)is tagged as a "serious error". In such cases
the adapter will give up its ability to be a bus master. In this situation
the host will still be able to read internal device registers in order to
generate an error report. A device reset is necessary to return to normal
operation.
- In the event of a pcix data parity error, the adapter will automatically
disable itself. Adapter_En will automatically transition from '1' to '0' and
the adapter will enter its clean-up routine. Once the device has achieved
quiescence, an adapter reset should be performed.
- Replaced alarm_intr_handler() with s2io_handle_errors().
- Added statistic counters to monitor the alarms.
[ Fix warnings wrt. do_s2io_chk_alarm_bit(), Callers pass in an
"unsigned long long *" but the function takes a "u64 *" which is
different on many 64-bit platforms. -DaveM ]
