[SCSI] lpfc: NPIV: add SLI-3 interface

Browse Source 
NPIV support is only available via new adapter interface extensions,
termed SLI-3. This interface changes some of the basic behaviors such
as command and response ring element sizes and data structures, as
well as a change in buffer posting.  Note: the new firmware extensions
are found only on our mid-range and enterprise 4Gig adapters - so NPIV
support is available only on these newer adapters. The latest firmware
can be downloaded from the Emulex support page.
