During heavy I/O (CPU-affinity mode enabled) and CLI/Agent
interactions, the driver would report periodic mailbox command
timeout statuses. Within the CPU-affinity ISR handler, the
driver should check the 'disable-msix-handshake' flag in deciding
whether or not to clear HCCRX_CLR_RISC_INT. The mode is not
specific to a dedicated queue, instead, applies to the current
'ha' context.

This fix:
- Disables app tag peeking; correct tag check will be added when the
SCSI API is available.
- Always derive ref_tag from scsi_get_lba()
- Removes incorrect swap of FCP_LUN in FCP_CMND
- Moves app-tag error check before ref-tag check. The reason being,
currently there is no interface in SCSI to retrieve the app-tag
for protection I/Os, so driver puts zero for app-tag in the
firmware interface, but requests not to validate it, but when a
ref-tag error is detected by firmware, it would put
expected/actual tags for all the protection tags (guard/app/ref).
As driver checks for app tag error first, a ref-tag error is
incorrectly flagged as app-tag error.
- Convert HBA specific checks to capability based.

Default is 0 - no logging. 0x40000000 - Module Init & Probe.
0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery.
0x08000000 - IO tracing. 0x04000000 - DPC Thread.
0x02000000 - Async events. 0x01000000 - Timer routines.
0x00800000 - User space. 0x00400000 - Task Management.
0x00200000 - AER/EEH. 0x00100000 - Multi Q.
0x00080000 - P3P Specific. 0x00040000 - Virtual Port.
0x00020000 - Buffer Dump. 0x00010000 - Misc.
0x7fffffff - For enabling all logs, can be too many logs.
Setting ql2xextended_error_logging module parameter to any of the above
value, will enable the debug for that particular level.
Do LOGICAL OR of the value to enable more than one level.

Currently when we receive a CS_RESET as a response for a SCSI command the
driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There
are certain circumstances where this could cause the mid-layer to exhaust all of
its retries if the FC port goes away for a short time. This will result in
commands being prematurly failed. Moving the CS_RESET return code to be
grouped with other link level events will cause the FC transport layer to block
that target's queue thus preventing the premature exhaustion of retries.

Migrate to a consistent set of debug entries during status-IOCB
handling:
* group CS_TIMEOUT handling with CS_PORT_UNAVAILABLE and the like
(more regrouping of common behaviour).
* drop CS_DATA_OVERRUN handling as it now falls into the
'default' case (still returns DID_ERROR).
* consolidate CS_RESET and CS_ABORTED handling, as we the only
functional difference was a printk() (still returns DID_RESET).
* dropped all the earlier inconsistent [qla_]printk()s sprinkled
throught the needlessly large case-statement. Failure case
I/Os are now logged with a 'standard' format:
<command failure details>
<command generic details>
so, for example a dropped-frame is logged as:
qla2xxx 0000:13:00.0: scsi(16:0:0) Dropped frame(s) detected (4000 of 4000 bytes).
qla2xxx 0000:13:00.0: scsi(16:0:0) FCP command status: 0x15-0x18 (70018) \
oxid=78 ser=76 cdb=280000 len=4000 rsp_info=0 resid=0 fw_resid=4000
which should now convey all relevant information.
