Pull SCSI updates from James Bottomley:
"This is the usual grab bag of driver updates (lpfc, hpsa,
megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.

There is also one new driver: the Cisco snic. The advansys driver has
been rewritten to get rid of the warning about converting it to the
DMA API, the tape statistics patch got in and finally, there's a
resuffle of SCSI header files to separate more cleanly initiator from
target mode (and better share the common definitions)"

lpfc: Fix to drop PLOGIs from fabric node till LOGO processing completes

2015-06-13T15:24:13+00:00

The domain controller PLOGI's concurrent with prior LOGO's/unreg_rpi's
completing created a race condition where driver rpi ref count can
inadvertantly hit 0 and the rpi attempted to be freed. This error
sometimes resulted in Warning messages indicating kref.h via
lfpc_nlp_get+0x128.

Correct by dropping any new PLOGI until the prior nport state has settled.

lpfc: Fix scsi task management error message.

2015-06-13T15:23:40+00:00

TMF's were getting error messages on FCP_RSP errors (underrun). Underruns
aren't meaningful in the scenario. Change the error message to filter out
these response check errors, and don't unconditionally mark the cmd as
in error.

lpfc: Fix cq_id masking problem.

2015-06-13T15:22:59+00:00

The driver inadvertainly constrained the id space to 8 bits, when its
a full 16 bits from hw. This resulted in bad id's being written to the
hardware. Resulted in symptoms such as incomplete initialization, no
detection of link events, etc.

2015-06-13T15:22:04+00:00

Didn't check for less-than-or-equal zero. Means we may later call
scsi_dma_unmap() even though we don't have valid mappings.

lpfc: Add support for using block multi-queue

2015-06-13T15:20:59+00:00

With blk-mq support in the mid-layer, lpfc can do IO steering based
on the information in the request tag.  This patch allows lpfc to use
blk-mq if enabled. If not enabled, we fall back into the emulex-internal
affinity mappings.

This feature can be turned on via CONFIG_SCSI_MQ_DEFAULT or passing
scsi_mod.use_blk_mq=Y as a parameter to the kernel.

lpfc: Devices are not discovered during takeaway/giveback testing

2015-06-13T15:20:30+00:00

When a remote nport changes it's DID, a new ndlp is used.
However, we left the old ndlp state unchanged and still in
a discovery state. The may stall discovery resulting in some
devices not being discovered.  Correct by swapping the state
of the 2 ndlp's when a DID swap is detected.

lpfc: Fix vport deletion failure.

2015-06-13T15:19:25+00:00

If a vport was deleted while in the middle of discovery, we weren't
clearing the nport discovery flag. Correct by clearing the flag and
cancelling our discovery timeout timer.
