loop-resync.
There were several issues here, one, during RSCN handling if a
follow-on RSCN occurred (within interrupt context) the DPC thread
could inadvertantly leave the fcport in a stale lost state.
Secondly, scheduled rport removal is handled exclusively by the
'parent' DPC thread, so wake up the proper thread. Finally,
process vport loop-resync's only when the vport has in an
"active" state (ID acquired).

The firmware group has suggested that FCE (Fibre Channel Event)
tracing be enabled prior to EFT (Extended Firmware Tracing) to
maximize the capturing of data on the wire. This change has no
real semantic effect on driver operation, as it's mostly a
shuffling of code.

Recent ISPs have this information written at manufacturing time,

iIDMA support requires the driver issue several additional
fabric-managegment (FM) commands per port discovered during SNS
scanning -- GFPN (Get Fabric Port Name) and GPSC (Get Port Speed
Capabilities). It has been found during testing that some
switches do not respond as *well* as expected to these commands
(silence -- no ACC nor BS_RJT). So, to handle such conditions,
allow the user the ability to indirectly disable the FM commands
by disabling iIDMA with the ql2xiidmaenable module-parameter.

Which shows that lockdep is detecting the driver's
interrupt-handler is run in both process and interrupt context
with irqs-enabled in the former case.
During init-time and error-recovery (after a RISC reset), the
driver disables interrupts and 'polls' for completions by calling
qla2x00_poll():
static inline void
qla2x00_poll(scsi_qla_host_t *ha)
{
ha->isp_ops->intr_handler(0, ha);
}
which in-turn calls the ISP registered interrupt handler. This
patch corrects it by disabling local interrupts during polling.
