Cisco has developed a new PCI HBA interface called sNIC, which stands for SCSI NIC. This is a new storage feature supported on specialized network adapter. The new PCI function provides a uniform host interface and abstracts backend storage. [jejb: fix up checkpatch errors] Signed-off-by:

If and when this gets enabled the driver could should split up IO memory space properly and that is quite a bit of work. Just remove the uncommented dead MTRR code then. There are a few motivations for this: a) Take advantage of PAT when available b) Help bury MTRR code away, MTRR is architecture specific and on x86 its replaced by PAT c) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442 titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()") Signed-off-by:

A user of scsi_track_queue_full should pass to the function a constant value untill the queue-depth changes, otherwise the internal logic in scsi_track_queue_full rejects the change. Other users of this function use a 'sdev->queue_depth - 1' as depth parameter, let's do the same. Signed-off-by:

This fixes a regression caused by commit d3557fc8 megaraid_sas : Add separate function for setting up IRQs This makes boot end with 'root does not exist' message on certain adapters. The bug is that the driver does not setup ints for cards without msi-x support. This patch fixes it, in addition to that it moves tasklet initialisation before enable_intr, otherwise a kernel panic may occur, when an interrupt arrives before the tasklet is ready. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

LCB requests to set Beacon would fail if the beacon was already enabled internally as the mailbox command used to query the state failes with an already-set status. Correct by enhancing the check so we don't fail if if the already set status comes back. Signed-off-by:

The order (it's a shall, but hard to dictate after the fact) is given in FC-SCM - kind of. SCM indicates what shall be implemented, lists it as (a), (b), (c), but actually doesn't say it has to be in that order. The only hard requirement, called out in FCP-4, is that you must register your FC-4 Type (via RFT_ID) before registering FC-4 Type Features (via RFF_ID), which makes sense. We obviously violated this and there were some switches (or newer fw in them) that enforced it. The other rule of thumbs are: register your data with the switch first, then register for SCRs, then do queries about the fabric, with the SCRs telling you of changes post the queries. Signed-off-by:
