d424754cbe [SCSI] qla2xxx: Correct inadvertent clearing of RISC_INTR status.
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.

9bfacd01dc [SCSI] qla2xxx: Fix crash in qla2x00_abort_all_cmds() on unload
I hit a crash in qla2x00_abort_all_cmds() if the qla2xxx module is
unloaded right after it is loaded.  I debugged this down to the abort
handling improperly treating a command of type SRB_ADISC_CMD as if it
had a bsg_job to complete when that command actually uses the iocb_cmd
part of the union.  (I guess to hit this one has to unload the module
while the async FC initialization is still in progress)

It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT,
SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.

e02587d777 [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.
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.

0x7fffffff - For enabling all logs, can be too many logs.

Setting ql2xextended_error_logging module parameter to any of the above

43ebf16d76 [SCSI] qla2xxx: Fix hang during driver unload when vport is active.
Bumping ref count during fc_vport_terminate() was the cause. vport
delete would wait for ref count to drop to zero and that would never
happen.

fa96d92736 [SCSI] qla2xxx: Properly set the dsd_list_len for dsd_chaining in cmd type 6.
The firmware spec has the fcp_data_dseg_len defined as a 32-bit
value, while the corresponding field in the driver structure has
it defined as a 16-bit value.

cefcaba67a [SCSI] qla2xxx: Fix virtual port failing to login after chip reset.
This patch ensures qla82xx_watchdog is not being run for the vport. It also
makes sure that beacon ON is not done for the vport, as it will lead to the
waking up of the dpc thread again and again.

ec426e106c [SCSI] qla2xxx: Log fcport state transitions when debug messages are enabled.
Add the inline function qla2x00_set_port_state() so that when a fcport state
transition happens we can log the state transition if debug messages are
enabled.

a4f92a32a0 [SCSI] qla2xxx: Verify login-state has transitioned to PRLI-completed.
Before driver's own internal state is marked as PLOGI/PRLI
complete. This additional check closes a window seen with
dual-personality initiator/target devices where a driver's
PLOGI/PRLI request occurs within the window after the target's
PLOGI request has completed, but prior to the target's PRLI
arriving and processed by the firmware. Without this additional
check, the firmware will return port-information stating that the
port neither supports target nor initiator functions, causing the
driver to register the rport prematurely to the FC-transport
without the proper 'roles' being set.
