39a550d2d9 qla2xxx: remove use of FC-specific error codes
The qla2xxx driver uses the FC-specific error when it needed to return an
error to the FC-NVME transport.  Convert to use a generic value instead.

cf19c45dba scsi: qla2xxx: Add command completion for error path
The driver held spinlocks during callbacks for NVME errors which
resulted in a deadlock because recovery LS cmds needed the same lock.

c345c6ca13 qla2xxx: Fix NVMe entry_type for iocb packet on BE system
This patch fixes incorrect assignment for entry_type field for Continuation
Type iocb packet on BE system. This was caught by -Woverflow warning on BE
system compilation.

For Continuation Type iocb driver needs to write complete 32 bit value to
initialize other field members in structure to 0.

Following warning is seen on BE system compile:

drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2x00_start_nvme_mq':
include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer
implicitly truncated to unsigned type [-Woverflow]
 #define __cpu_to_le32(x) ((__force __le32)__swab32((x)))

[mkp: fixed typo]

bcda771b2f scsi: qla2xxx: avoid unused-function warning
When NVMe support is disabled, we get a couple of harmless warnings:

drivers/scsi/qla2xxx/qla_nvme.c:667:13: error: 'qla_nvme_unregister_remote_port' defined but not used [-Werror=unused-function]
drivers/scsi/qla2xxx/qla_nvme.c:634:13: error: 'qla_nvme_abort_all' defined but not used [-Werror=unused-function]
drivers/scsi/qla2xxx/qla_nvme.c:604:12: error: 'qla_nvme_wait_on_rport_del' defined but not used [-Werror=unused-function]

This replaces the preprocessor checks in the code with equivalent
compiler conditionals, which lets gcc drop the unused functions without
warning, and is nicer to read.

e84067d743 scsi: qla2xxx: Add FC-NVMe F/W initialization and transport registration
This code provides the interfaces to register remote and local ports of
FC4 type 0x28 with the FC-NVMe transport and transports the requests
(FC-NVMe FC link services and FC-NVMe commands IUs) to the fabric. It
also provides the support for allocating h/w queues and aborting FC-NVMe
FC requests.
