bna: Update the Driver to v3.2.23.0

This patch set consists of feature additions like s/w timestamping support,
multi-buffer RX, firmware patch simplification, enhancements for RX filters,
RX processing changes, bug fixes and updates the firmware version to v3.2.3.0.
The patch set addressed the review commnets recieved.

This patch set updates the BNA driver to v3.2.23.0 and was tested against
net-next 3.12.0-rc6 kernel.

This patch includes change to enable firmware patch simplication feature.
This feature is targeted to address the requirement to have independent patch
release for firmware. Prior to the 3.2.3.0 firmware, releasing a patch fix for
firmware would require changes to bna driver, to use new firmware images.
However with these changes, if the new firmware is flashed on to the Adapter,
the driver will use the new firmware after checking the patch release byte in
the firmware version.

Update the f/w version to 3.2.3.0

Currently we already check to see whether the BNAD_TXQ_TX_STARTED cleared.
But if the tcb structure which contains this flag is also already freed by that
time, we would dereference the NULL pointer. This patch is to check tcb for NULL
pointer, before dereferencing it.

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.

 - Clear mac->handle before adding it to free_q.
 - bnad_set_rx_mode() rewritten. bnad_set_rx_mode() adds the MACs in uc_list
   to UCAM. If it exceeds the max supported, DEFAULT mode is turned on. If
   MCAM limit is exceeded, ALLMULTI mode is turned on.
 - Clear CF flags, check for the new mode and reprogram the Rx approach.

Change Details:

   Modify bna_rx_mcast_listset() implementation to not use only half of the
   limit.
 - Allocate and initialize queue for deleting
 - Segregate the adding and deleting process by using separate queues.
 - The filter framework in bna does not let adding addresses to its max capacity
   due to asynchronous operations involved.
   Provide a synchronous option to set a given list.

net: Add rxhash utility hash functions

v3:

There's really nothing specific about rxhash that constrains
it to be a value just for these receive path. Drop the 'rx'
part in utility functions, including skb_get_rxhash. In subsequent
patches, we can change the rxhash and l4_rxhash names also, as
well as abstracting out the interface to the hash.

Added comments about hash types per feedback.

In this version I'm omitting the changes to drivers to make the
patch set manageable. Will add those changes in followup pathes.

-----
This patch series introduce skb_set_rxhash and skb_clear_rxhash
which are called to set the rxhash (from network drivers) and
to clear the rxhash. This API should be used instead of updating
fields in the skbuff directly.

In several places 'skb->rxhash = 0' is being done to clear the
rxhash value in an skb.  This does not clear l4_rxhash which could
still be set so that the rxhash wouldn't be recalculated on subsequent
call to skb_get_rxhash.  This patch adds an explict function to clear
all the rxhash related information in the skb properly.

skb_clear_hash_if_not_l4 clears the rxhash only if it is not marked as
l4_rxhash.

Fixed up places where 'skb->rxhash = 0' was being called.
