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

Change details:
- When bnad_setup_tx() returns NULL, the error is NOT returned to the caller.
The caller will incorrectly assume success. So Return ENOMEM when bna_tx_create()
fails.
- If bnad_tx_msix_register() fails, call bna_tx_destroy() to free tx & to NULL
the bnad reference to tcb.

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.

Change Details:
- Added bna_rx_ucast_listset() for synchronous ucast listadd operation.
- 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.
- Added bnad_set_rx_ucast_fltr() and bnad_set_rx_mcast_fltr().

Change Details:

pending Qs rendering it non-deterministic of giving an upper limit.
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.

Any user-initiated path which eventually calls reset needs
to hold the rtnl_lock, so add functionality to do that.
Be careful not to use the safe reset when cleaning up
from the diagnostic tests, which avoids rtnl_lock
recursion from ethtool.
Protect the reset_task with rtnl_lock, since it runs from a work item.

The current driver default sets the number of transmit/receive
queue pairs based on the current node's CPU count.
A better method is to use the total number of CPUs in the system
to suggest the number of queue pairs, which aligns better with
the behavior of ixgbe, and also with the expectations of the
kernel XPS and other subsystems in the stack.

When the ethtool testing starts it sets the I40E_TESTING state
bit, which blocks new netdev opens so that things don't get
confused, while the testing might be messing with register and
other things. Unfortunately, that was keeping the PF resets
after the register test from working correctly because the netdev
would not get reopened. This patch reorders the tests to put the
register test last as it is the only one that needs a reset, and
we wait to trigger the reset until after we clear the
I40E_TESTING bit.

Currently a higher priority client can remove a lower priority
client's filter with equal match-expression. This might happen if (a)
the higher priority client has a double-free bug, or (b) another
client with sufficient priority replaced and then removed an equal
filter, allowing the low priority client to insert an equal filter.
In neither case does it actually make sense to carry out the removal;
we should say the filter doesn't exist, as the filter currently
present is not the one that the high-priority client is referring to.

MAC filters inserted automatically by the driver, based on the device
address list (EF10) or no-match filters (Siena), should be overridable
at MANUAL or REQUIRED priority. Currently they themselves have
REQUIRED priority and this requires some odd special-casing.
We also can't reliably tell whether such a MAC filter has or has
not been overridden. We just remember that it is wanted by the
stack (RX_STACK flag).
Add another priority level, AUTO, between HINT and MANUAL, and
use this for the automatic filters while they have not been
overridden. Remove the RX_STACK flag. Add an RX_OVER_AUTO
flag which is set only when an AUTO filter has been overridden
(or was requested to be inserted while a higher-priority filter
existed).

The SFC9100 family has only one clock per controller, shared by all
functions. Therefore only create a clock device under the primary
function, and make all other functions refer to the primary's clock
device.
Since PTP functionality is limited to port 0 and PF 0 on the earlier
SFN[56]322F boards, and we also set the primary flag for that
function, we can make the creation of a clock device conditional only
on this flag.
