66184b6b25 qla2x00t-32gbit: make 1-bit bit-fields unsigned int 
The bitfields mpi_fw_dump_reading and mpi_fw_dumped are currently signed
which is not recommended as the representation is an implementation defined
behaviour.  Fix this by making the bit-fields unsigned ints.

582746f829 qla2x00t-32gbit: Fix MPI failure AEN (8200) handling 
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)

7924ccd89c qla2x00t-32gbit: Serialize fc_port alloc in N2N 
For N2N, fc_port struct is created during report id acquisition.  At
later time, the loop resync (fabric, n2n, loop) would trigger the rest
of the login using the created fc_port struct.  The loop resync logic
can trigger another fc_port allocation if the 1st allocation was not
able to execute.  This patch prevents the 2nd allocation trigger.

NPIV re-enable code was blocked after FW had been initialized.  The
blocking check was too broad. Reduce the check to make sure if FW is
initialized or not.

44ab6ef708 qla2x00t-32gbit: Force semaphore on flash validation failure 
For single port 28XX adapter, the second core can still run in the
background.  The flash semaphore can be held by the non-active core.
This patch tell MPI FW to check for this case and clear the semaphore
from the non-active core.

44b99951e2 qla2x00t-32gbit: Update BPM enablement semantics. 
commit e4e3a2ce9556 ("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.
