ab053c09ee scsi: qla2xxx: Cast explicitly to uint16_t / uint32_t
Casting a pointer to void * and relying on an implicit cast from void *
to uint16_t or uint32_t suppresses sparse warnings about endianness. Hence
cast explicitly to uint16_t and uint32_t. Additionally, remove superfluous
void * casts.

3c75ad1d87 scsi: qla2xxx: Remove defer flag to indicate immeadiate port loss
During cable pull test case, if the port is disconnected for time larger
than devloss timeout, driver does not mark path offline.  In such case,
instead of notifying SCSI-ML of loop down, driver goes into endless loop of
device relogin because defer flag is set.

With newer handling of device relogin in driver discovery, defer flag is
now redundant. This patch removes defer flag and cleans up code handling
port lost indication to SCSI-ML.

 going to be that we're (again) trying to switch to mulitqueue as the

 Microchannel drivers, an update of the internal timers and some

Move this initialisation before each call to qla2x00_init_timer().  In some

7867b98dce scsi: qla2xxx: Fix memory leak in dual/target mode
When driver is loaded in Target/Dual mode, it creates QPair to support
MQ and allocates resources for each QPair. This Qpair initialization is
delayed until the FW personality is changed to Dual/Target mode by
issuing chip reset. At the time of chip reset firmware is re-initilized
in correct personality all the QPairs are initialized by sending
MBC_INITIALIZE_MULTIQ (001Fh).

This patch fixes memory leak by adding check to issue
MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the
flag is set for initiator mode, and clean up QPair resources correctly
during the driver unload. This MBX does not need to be issued for
Target/Dual mode because chip reset will reset ISP.

c38d1baff8 scsi: qla2xxx: Use ql2xnvmeenable to enable Q-Pair for FC-NVMe
In some environments, user can choose to not enable SCSI-MQ but wants to
use FC-NVMe feature of the driver. Since driver relies on Q-Pairs to
allocate FC-NVMe resources, use existing module parameter to create
Q-Pairs when FC-NVMe is enabled.

d65237c7f0 scsi: qla2xxx: Fix mailbox failure while deleting Queue pairs
In target mode driver, queue pairs are not created during driver load
time, instead they are created at the configuration time after chip
reset.  If a user tries to load/unload driver after queue pairs are
created, then there would be mailbox failure, while deleting queue
pairs.  Flag is added to check if queue pairs are created or not. Queue
pairs will be deleted only If they were created during target
configuration.

[ Upstream Commit 84e32a06f4 ]

Commit 84e32a0 ("qla2xxx: Use pci_enable_msix_range() instead of
pci_enable_msix()") introduced a regression when target mode is enabled.
In qla24xx_enable_msix(), ha->max_rsp_queues was incorrectly set
to a value higher than the number of response queues allocated causing
an invalid dereference. Specifically here in qla2x00_init_rings():
    *rsp->in_ptr = 0;

Add additional check to make sure the pointer is valid. following

On some vendor switches, when switch port is toggled (down /up),
then in some condition driver tries to configure virtual port,
before FW is actually in ready state to process any commands on wire.
At this time, configuring virtual port can fail. Add fix in driver
to make driver wait, for FW to be ready state before
