This function was added to encapsulate freeing the memory for all the fcports
associated with a particular vha. Also added a call to qla2x00_free_fcports()
to qla2x00_free_device() to free the memory for all the fcports associated with
a vha during device removal.

The default method that qla2xxx uses is the GID_PT nameserver command to
get a list of Nx_Ports. This patch adds a GFF_ID call for each port
returned by GID_PT to get the FC4 type. If the FC4 type is not FCP SCSI
then the qla2xxx driver will not record that port in it's port database.
For switches that do not support the GFF_ID command, the behavior will be
for qla2xxx to store that port anyways.

Currently we can only issue the task management (TM)
commands via the mailbox mechanism. This is a limitation,
since only one mailbox command can be issued at a time.
The purpose of this effort is to provide support for
issuing and processing the respose to TM and Marker
IOCBs asynchronously. Towards achieving this, the
consolidated srb architecture that is currently used for
BSG and IOCB/Logio commands has been enhanced and used.

Changing a lun's queue depth (/sys/block/sdX/device/queue_depth)
isn't sticky when the device is connected via a QLogic fibre
channel adapter.
The QLogic qla2xxx fibre channel driver dynamically adjusts a
lun's queue depth. If a user has a specific need to limit the
number of commands issued to a lun (say a tape drive, or a shared
raid where the total commands issued to all luns is limited at
the controller level, for example) and writes a limiting value to
/sys/block/sdXX/device/queue_depth, the qla2xxx driver will
silently and gradually increase the queue depth back to the
driver limit of ql2xmaxqdepth. While reducing this value (module
parameter) or increasing the interval between ramp ups
(ql2xqfullrampup) offers the potential for a work around it would
be better to have the option of just disabling the dynamic
adjustment of queue depth.
This patch implements an "off switch" as a module parameter.

to loading this firmware if the request-firmware interface failed
