It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a
PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an
sp->type SRB_SCSI_CMD which is invalid and should not be possible.
Reading the entry_type from the crash dump shows the expected value of
STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is
used.
Add a check to verify for consistency and reset the HBA if an invalid state
is reached. Obviously, this is only a workaround until the real problem is
solved.

Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular
firmware dump is also taken and then chip reset. This is disruptive to IOs
and not required. Make the firmware dump collection, followed by chip
reset, optional (not done by default).
Firmware dump buffer and MPI dump buffer are independent of each
other with this change and each can have dump that was taken at two
different times for two different issues. The MPI dump is saved in a
separate buffer and is retrieved differently from firmware dump.
To collect full dump on MPI failure AEN, a module parameter is
introduced:
ql2xfulldump_on_mpifail (default: 0)

commit e4e3a2ce95 ("scsi: qla2xxx: Add ability to autodetect SFP
type") takes a heavy handed approach to BPM (Buffer Plus Management)
enablement:
1) During hardware initialization, if an LR-capable transceiver is
recognized, the driver schedules a disruptive post-initialization
chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the
firmware. This chip-reset will result in (short-term) path-loss to
all fc-rports and their attached SCSI devices.
2) LR-detection is triggered during any link-up event, resulting in a
refresh and potential chip-reset
Based on firmware-team guidance, upon LR-capable transceiver
recognition, the driver's hardware initialization code will now
re-execute firmware with the new BPM settings, then continue on with
driver initialization. To address the second issue, the driver
performs LR-capable detection upon the driver receiving a
transceiver-insertion asynchronous event from firmware. No short-term
path loss is needed with this new semantic.

Since the SCSI core does not reuse the tag of the SCSI command that is
being aborted by .eh_abort() before .eh_abort() has finished it is not
necessary to check from inside that callback whether or not the SCSI
command has already completed. Instead, rely on the firmware to return an
error code when attempting to abort a command that has already
completed. Additionally, rely on the firmware to return an error code when
attempting to abort an already aborted command.
In qla2x00_abort_srb(), use blk_mq_request_started() instead of
sp->completed and sp->aborted.

Abort will tell FW to release the command from FW possesion. The original
command will return to ULP with error in its normal fashion via scsi_done.
eh_abort path would wait for the original command completion before

Instead of calling qla2x00_fcport_event_handler() and letting the switch
statement inside that function decide which other function to call, call
the latter function directly. Remove the event member from the event_arg
structure because it is no longer needed. Remove the
qla_handle_els_plogi_done() function because it is never called.

The C language supports implicit casting of void pointers to non-void
pointers. Remove explicit sts_entry_* casts that are not necessary.

Not calling sp->done() from the command completion path is a severe bug.
Hence complain loudly if that happens.

Read the FC port state once instead of twice. This patch fixes the
following Coverity complaint:
Unchecked return value (CHECKED_RETURN)
check_return: Calling atomic_read without checking return value (as is
done elsewhere 80 out of 92 times).
