bna: Enable Multi Buffer RX

The CT2 HW supports multi-buffer Rx. This patch provides the necessary changes
for bnad to use multi-buffer Rx feature. For BNAD, multi-buffer Rx is by
default enabled when MTU is > 4096. For >4096 MTU, q0 data/large buffers are of
2048 size. As the resource requirements of multi-buffer Rx are different new Rx
needs to be created to use this feature. ASIC posts multiple completions if
frame exceeds buffer size. The last completion is marked with EOP flag.
- Separate HQ and DQ enums for resource allocations and configurations.
- rx_config and rxq structure changes to pass the correct info from bnad.
- DQ depth need not be same as HQ depth. So CQ depth is adjusted accordingly.
- Rx CFG frame size is taken from configured MTU.
- Rx q0 buffer size is configured from bnad s rx_config when multi-buffer is
enabled.
- Poll for entire frame completion.
- Once EOP completion is received gather the number of vectors used by the
frame to submit it to the stack.
- Changed MTU to frame size wherever necessary.

bna: Firmware update

Change Details:
- Added Stats clear counter to the bfi_enet_stats_mac structure and
ethtool stats
- Modified the firmware naming convention to contain the firmware image
version (3.1.0.0). The new convention is
<firmware-image>-<firmware-version>.bin The change will enforce loading
only compatible firmware with this driver and also avoid over-writing
the old firmware image in-order to load new version driver as the
firmware names used to be the same.

bna: Introduce ENET as New Driver and FW Interface

Change details:
- This patch contains the messages, opcodes and structure format for the
messages and responses exchanged between driver and the FW. In addition
this patch contains the state machine implementation for Ethport, Enet,
IOCEth.
- Ethport object is responsible for receiving link state events, sending
port enable/disable commands to FW.
- Enet object is responsible for synchronizing initialization/teardown of
tx & rx datapath configuration.
- IOCEth object is responsible for init/un-init of IO Controller in the
adapter which runs the FW.
- This patch also contains code for initialization and resource assignment
for Ethport, Enet, IOCEth, Tx, Rx objects.
