- Added support to collect and reset fcport stats.
- Modified design to allow multiple requests for fcport stats.
  - fcport will remember the stats request in its stats_pending
    queue and service each of the queued requests after receiving
    a firmware response for the prior request.

- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
  needed by all the BFA sub-modules as one contiguous chunk.

- If flash controller is halted unconditionally, this results in
  illegal write access to flash controller register domain. Since
  flash controller registers are only accessible once s_clk is started
  - added logic to check for WGN status and halt flash controller only
  if it is already running.
- Added check to wait for flash controller halt to be completed before
  proceeding with s_clk/l_clk initializations.
- Removed unnecessary reset logic for PMM 1T memory and moved memory
  initialization after flash access enable.
- Disable Brocade-1860 asic MBOX interrupt before PLL initialization.
- Remove reset enable for S_CLK/L_CLK after both PLL initializations
  are complete.

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.

- Added new asic based card types and modified IOC get card model routine.

- 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.

Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get
a notification and hence are not cleanly shutdown. So registers holding
driver/IOC state information are not reset back to valid disabled/parking
values. This causes subsequent driver initialization to hang during kdump
kernel boot.

Fix description: during the initialization of first PCI function, reset
corresponding register when unclean shutown is detect by reading chip
registers. This will make sure that ioc/fw gets clean re-initialization.
