transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Modify intialization semantics:
- perform basic hardware configuration only (as usual)
- allocate resources
- load and execute firmware
- defer link (transport) negotiations to the DPC thread
- again the code in qla2x00_initialize_adapter() to stall probe()
completion was needed for legacy-style scanning.
- DPC thread stalls until probe() complete.
- before probe() completes, set DPC flags to perform loop-resync logic
(similar to what's done during cable-insertion/removal).
Benefits: user does not have to wait 20+ seconds in case the FC cable
is unplugged during driver load, code consolidation (removal of
redundant link negotiation logic during initialize_adaoter()), and
finilly, the driver no longer needs to defer the fc_remote_port_add()
calls to hold off lun-scanning prior to returning from the probe()

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state. This issue can result in a hung PCIe
link. Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.
In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully. In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.

iIDMA (Intelligent Interleaved Direct Memory Access) allows for
the HBA hardware to send FC frames at the rate at which they can
be received by a target device. By taking advantage of the
higher link rate, the HBA can maximize bandwidth utilization in a
heterogeneous multi-speed SAN.
Within a fabric topology, port speed detection is done via a Name
Server command (GFPN_ID) followed by a Fabric Management command
(GPSC). In an FCAL/N2N topology, port speed is based on the HBA
link-rate.

[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.
and given:
- the process-context requirements of the FC transport

- lack of port-type RSCN processing logic for ISP24xx and newer
chips.
it's time now to remove the state-machine logic from mainline.

In qla2x00_reset_chip the driver first takes the hardware lock,
and then later on takes the mbx lock.
In the mailbox_command code.. it goes the other way around.
Discovered with the lock validator.

ISP24XX FW does not support Mbx 0x74 ie Login Local Port.
Added the equivalent code for ISP24XX ie to relogin in non
fabric case for ISP24XX use login iocb.
