Driver was incorrectly using the SLAB_CACHE_DMA flag when creating a cache
for SGLs. fnic device does not have 24-bit DMA restrictions. Remove the flag
and allocations from ZONE_DMA.

Thanks to Roland Dreier and David Rientjes for pointing out the bug.

- Moved FCS initialization, which internally does the im_port creation
  as well as the scsi_host creation before bfa_init.

Once the bfa_init is complete & successful:
- Reset the FCS base port cfg params such as pwwn/nwwn and setup fc host
  params - based on the values learned during the ioc getattr request.
- Change needed to support BSG commands even on bfa init failure.
- Model description fixes for Brocade adapters.

- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.

Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
  timer calibration (around 300 miilisecs earlier). So there is a
  window if an accept comes during this time HBA would have initiated
  an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.

- Added support for 16Gbps.
- Added logic to flush pending mailbox command queue when IOC is disabled.
- Fix to Halt the flash controller during fw initialization - since
  when asic blck is programmed flash controller's continuous access
  blocks f/w access to flash.
- Added new asic based card types and modified IOC get card model routine.
- Added PLL init fix to do LPU reset every time we do a memory
  initialization, since not doing so will cause LPU to be
  uninitialized during driver load.
- Added fix to Halt flash controller before PLL initialization.

- Introduced IOC poll mechanism which replaces current interrupt
  based FW READY method.
- The timer based poll routine in IOC will query the ioc_fwstate
  register to see if there is a state change in FW, and sends the READY event.
- Bug fixes in the new asic PLL initialization.
- Added logic to handle CPE/RME queue interrupts before iocfc config done.
  1. Use the queue_process flag to see if iocfc configuration is done
     in INTX mode.
  2. Split the MSIX handler installation in two - one for IOC intr
     handler and the other for cpe/rme queue handler - and delay
     assigning queue handlers until iocfc config is done in MSIX mode.

Noticed that when the sysfs interface of the SCSI SES
driver was used to request a fault indication the LED
flashed but the buzzer didn't sound. So it was doing
what REQUEST IDENT (locate) should do.

Changelog:
   - fix the setting of REQUEST FAULT for the device slot
     and array device slot elements in the enclosure control
     diagnostic page
   - note the potentially defective code that reads the
     FAULT SENSED and FAULT REQUESTED bits from the enclosure
     status diagnostic page

Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone
as the physical port and shares the same LUN. This happens due to the fact that
vport destroy and unsolicited ELS are scheduled to run on the same workqueue,
and vport destroy destroys the lport and the unsolicited ELS tries to access
the invalid lport.  This patch fixes this issue by maintaining a list of valid
lports and verifying if the lport is valid or not before accessing it.
