1. While FRU VPD data update, inform firmware to send a completion event
on I2C bus. Without this change, firmware used to send completion
message on I2C bus for every chunk of FRU VPD update.
2. Support for FRU VPN update on CHINOOK2 cards.
3. Append port count to the model name to differentiate between single
port and dual port model of 1860.
4. Update the size of the model name to 16bytes

Root cause: When kernel crashes, On brocade 815/825 adapters,
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 fail
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.

D-Port is a new port type created with the intention of running link
level diagnostic tests like loopback, traffic test. In static D-port
mode, user configures the port to D-port mode and starts the test, but
in dynamic D-port, once the Brocade switch port is configured to
D-port, it will reject the regular FLOGI from HBA with reason that it is
in D-port mode. So based on the reason code HBA port will turn itself into
D-port and start diagnostic test.

- Introduced support for D-Port which is a new port mode during which
link level diagnostics can be run.
- Provided mechanism to dynamically configure D-Port and initiate diagnostic
tests to isolate any link level issues.
- In D-Port mode, the HBA port does not participate in fabric or login to the
remote device or run data traffic.
- Diagnostic tests include running various loopback tests in conjunction with
the attached device.

- 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.

- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
in the message header and firmware modules use h/w queue ID from
message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
messages. Used to translate host tag to firmware tag. bfa_lpuid()
is changed to bfa_fn_lpu() that encodes both PCI function and port
ID in BFI message header.

- 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.

- Introduced IOC poll mechanism which replaces current interrupt

- 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.
