[PATCH 04/17] qla2xxx: Use GFF_ID to check FCP-SCSI FC4 type before logging into Nx_Ports

[giridhar.malavali]

From: Chad Dupuis <chad.dupuis@qlogic.com>

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.

[PATCH 06/17] qla2xxx: Correct extended sense-data handling.

From: Andrew Vasquez <andrew.vasquez@qlogic.com>

Earlier implementation did not take into account the varying
sizes of data buffers returned from structures sts_entry_t and
sts_entry_24xx.  Sense-data after the 20th byte could be
incorrect.

[PATCH 08/17] qla2xxx: Stop firmware before doing init firmware.

[giridhar.malavali]

From: Andrew Vasquez <andrew.vasquez@qlogic.com>

If BIOS is enabled then drivers init firmware fails since
BIOS has done the init once.

[PATCH 09/17] qla2xxx: Add qla2x00_free_fcports() function

[giridhar.malavali]

From: Chad Dupuis <chad.dupuis@qlogic.com>

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.
