* lpfc: Fix to drop PLOGIs from fabric node till LOGO processing completesJames Smart2015-06-131-1/+1
| | | | | | | | | | | | | | | 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: Add support for using block multi-queueJames Smart2015-06-131-51/+23
| | | | | | | | | | | | | | | 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: Fix premature release of rpi bit in bitmaskJames Smart2015-04-101-3/+46
| | | | | | | | | | | | | | | | Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

* lpfc: Add iotag memory barrierJames Smart2014-05-191-0/+21
| | | | | | | | | | | | | | | | | | | | | | | Add a memory barrier to ensure the valid bit is read before any of the cqe payload is read. This fixes an issue seen on Power where the cqe payload was getting loaded before the valid bit. When this occurred, we saw an iotag out of range error when a command completed, but since the iotag looked invalid the command didn't get completed to scsi core. Later we hit the command timeout, attempted to abort the command, then waited for the aborted command to get returned. Since the adapter already returned the command, we timeout waiting, and end up escalating EEH all the way to host reset. This patch fixes this issue.
