This patch uses dma_map_sg with phba->pcidev->dev instead of
scsi_dma_map.

scsi_dma_map doesn't work for NPIV since fc_vport->dev isn't fully
initialized. check_addr() in arch/x86_64/kernel/pci-nommu.c leads to
the crash since dev->dma_mask is NULL.

The Dell PERC2/QC erroneously was listed as having the 31 bit limit
quirk on the interface allocations, removing the reference to repair
this oversight. Also, the 2 quad pci address (family) match catch-all
also retained the 31 bit limit and the 34 SG limit quirks in a paranoid
move. Now, many years later, we find that none of the Adapters that did
trigger with the family match had such quirks; these quirks are all
limited to the 4 quad pci address matches to select legacy adapters
already populated.

 in the testing and qualification of the driver:

 - Fix affinity of ELS ring to slow/deferred event processing
 - Fix Ring attention masks
 - Defer dev_loss_tmo timeout handling to worker thread
 - Consolidate link down error classification for better error checking
 - Remove unused/deprecated nlp_initiator_tmr timer
 - Fix for async scan - move adapter init code back into pci_probe_one
   context. Fix async scan interfaces.
 - Expand validation of ability to create vports
 - Extract VPI resource cnt from firmware
 - Tuning of Login/Reject policies to better deal with overwhelmned targets
 - Misc ELS and discovery fixes
 - Export the npiv_enable attribute to sysfs
 - Mailbox handling fix
 - Add debugfs support
 - A few other small misc fixes:

 - Added adapter failure heartbeat

NPIV support is added to the driver.  It utilizes the interfaces of
the fc transport for the creation and deletion of vports. Within the
driver, a new Scsi_Host is created for each NPIV instance, and is
paired with a new instance of a FC port.  This allows N FC Port
elements to share a single Adapter.
