Rework the lpfc_printf_log() macro so that logging is enabled on a
per-vport basis. Used to be on a physical-port basis, thus logging
with large numbers of vports became a mess. Required redefinition of
the macro, and an update of every use.

Following the NPIV support, the following changes have been accumulated
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:
- wrong return values, double-frees, bad locking
- 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.

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.

The driver is reorganized to separate the handling of the adapter from
the handling of the FC port. Adapter handling includes submissions of
command requests, receiving responses, and managing adapter resources.
The FC port includes the discovery engine, login handling, and the
mapping of a Scsi_Host on the "port". Although not a large functional
change, as it touches core structures and functions, resulting in a
large text delta.

Replace use of lpfc_put_lun with midlayer's int_to_scsilun
Remove driver's local definition of lpfc_put_lun (which converts an
int back to a 64-bit LUN) and replace it's use with the recently added
int_to_scsilun function provided by the midlayer.
Note: Embedding midlayer structure in our structure caused
need for more files to include midlayer headers.

Fix panic in lpfc_get_stats()
Symptoms: Panic on sysfs stats access
Cause: In lpfc_get_stats() we are writing to memory that we do not
own.
Fix: Fix our stats structure allocation. Embed phba->link_stats in
struct lpfc_hba and stop treating it like rogue structure.
Note: Embedding midlayer/transport structure in our structure caused
need for more files to include midlayer/transport headers.
