d4781807f0 scsi: qla2xxx: Fix unused variable warning in qla2xxx_process_purls_pkt()
When CONFIG_NVME_FC is not set, fcport is unused:

  drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2xxx_process_purls_pkt':
  drivers/scsi/qla2xxx/qla_nvme.c:1183:20: warning: unused variable 'fcport' [-Wunused-variable]
   1183 |         fc_port_t *fcport = uctx->fcport;
        |                    ^~~~~~

While this preprocessor usage could be converted to a normal if
statement to allow the compiler to always see fcport as used, it is
equally easy to just eliminate the fcport variable and use uctx->fcport
directly.

The storage was not draining I/Os and the work load was not spread out
across different CPUs evenly. This led to firmware resource counters
getting overrun on the busy CPU. This overrun prevented error recovery from
happening in a timely manner.

By switching the counter to atomic, it allows the count to be little more
accurate to prevent the overrun.

5b51f35d12 scsi: qla2xxx: Fix erroneous link up failure
Link up failure occurred where driver failed to see certain events from FW
indicating link up (AEN 8011) and fabric login completion (AEN 8014).
Without these 2 events, driver would not proceed forward to scan the
fabric. The cause of this is due to delay in the receive of interrupt for
Mailbox 60 that causes qla to set the fw_started flag late.  The late
setting of this flag causes other interrupts to be dropped.  These dropped
interrupts happen to be the link up (AEN 8011) and fabric login completion
(AEN 8014).

Set fw_started flag early to prevent interrupts being dropped.

da7c21b72a scsi: qla2xxx: Fix command flush during TMF
For each TMF request, driver iterates through each qpair and flushes
commands associated to the TMF. At the end of the qpair flush, a Marker is
used to complete the flush transaction. This process was repeated for each
qpair. The multiple flush and marker for this TMF request seems to cause
confusion for FW.

Instead, 1 flush is sent to FW. Driver would wait for FW to go through all
the I/Os on each qpair to be read then return. Driver then closes out the
transaction with a Marker.

ultimately being used inside a union:

drivers/scsi/qla2xxx/qla_def.h:
3240 struct ct_sns_gpnft_pkt {

3243                 struct ct_sns_gpnft_rsp rsp;
3244         } p;
3245 };

Refactor the rest of the code, accordingly.

d54820b22e scsi: qla2xxx: Fix NULL pointer dereference in target mode
When target mode is enabled, the pci_irq_get_affinity() function may return
a NULL value in qla_mapq_init_qp_cpu_map() due to the qla24xx_enable_msix()
code that handles IRQ settings for target mode. This leads to a crash due
to a NULL pointer dereference.

This patch fixes the issue by adding a check for the NULL value returned by
pci_irq_get_affinity() and introducing a 'cpu_mapped' boolean flag to the
qla_qpair structure, ensuring that the qpair's CPU affinity is updated when
it has not been mapped to a CPU.
