c696cc6593 net/bnxt: fix race condition when port is stopped
Fix a race condition between port stop and error recovery task. When io
forwarding is not started on Stingray devices, driver will not receive
the async event from FW when there is a FW reset. While exiting testpmd,
as part of port stop driver sees this event and this in turn causes a
race between port stop and error recovery task.

Fixed this by ignoring the fatal/non-fatal async event from FW while
stopping port.

f0f6b5e6cf net/bnxt: fix reusing L2 filter
The software L2 filter was being released back to the free pool,
though it was created in HW and the filter corresponding to an actual
'flow' would have reference to the HW L2 filter.
But if this 'flow were to be deleted, then this HW L2 filter also
would be gone.
Fix this by storing the L2 filter created originally either for an
n-tuple flow or otherwise as part of the vnic's filter list.
This would require the filter_info struct to have a backptr to the
vnic which it came from.
Now that L2 filters can be re-used for an n-tuple filter(s), delete
L2 filter as well so the reference count of an L2 filter (if reused)
can be decremented appropriately.

5c63167168 net/bnxt: fix non matching flow hitting filter rule
As part of ntuple filter, we were creating L2 filter with the ntuple
redirect queue resulting in any L2 matching flow getting steered to
this queue. For ntuple filters, we need to create the L2 filter with
default queue. The user specified redirect queue will be set while
creating the ntuple filter in hardware.

e339ef6e35 net/bnxt: fix flow flush to sync with flow destroy
Sync flow flush routine with flow destroy so that the operations
performed per flow during a flush are the same as that are done for an
individual flow destroy by having a common function to call for both.
One of the things that was missed in the flow flush routine was the
deletion of the L2 filter that would have been created as part of an
n-tuple filter.
Also, decrement the l2_ref_cnt for a filter in the case of a filter
update as it would've bumped up previously in validate_and_parse_flow()

816eacad11 net/bnxt: fix Tx queue profile selection
In the case when CoS classification is disabled, driver was iterating
looking for only lossy profiles as that is what is expected to be used
for regular NIC operations. But in certain custom profiles, there were
no lossy profiles configured, only lossless profiles instead.
To handle such cases, it is better to fallback to using the first valid
profile.
