[dpdk-stable] [PATCH v3 1/7] net/bnxt: fix link failure during port toggle

[Ajit Khaparde]

From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>

We need to wait for up to 500ms to receive async event notification after
forcing link down. Similarly we need to wait for up to 10s for link to
come up after configuring the hardware for link up.

[dpdk-stable] [PATCH v3 2/7] net/bnxt: fix to use first valid profile

[Ajit Khaparde]

From: Somnath Kotur <somnath.kotur@broadcom.com>

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.

[dpdk-stable] [PATCH v3 3/7] net/bnxt: fix flow flush to sync with flow destroy

[Ajit Khaparde]

From: Somnath Kotur <somnath.kotur@broadcom.com>

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()

[dpdk-stable] [PATCH v3 4/7] net/bnxt: fix non matching flow hitting filter rule

[Ajit Khaparde]

From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>

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.

[dpdk-stable] [PATCH v3 5/7] net/bnxt: fix to reuse an L2 filter

[Ajit Khaparde]

From: Somnath Kotur <somnath.kotur@broadcom.com>

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.

[dpdk-stable] [PATCH v3 7/7] net/bnxt: fix to not overwrite error message

[Ajit Khaparde]

In some cases when flow creation fails, we  overwrite the specific
error message with a generic error message. This patch fixes it.

Fixes: d24610f7bfda ("net/bnxt: allow flow creation when RSS is enabled")

The result will be same as far as I can see, you may get rid of the "rc =
-rte_errno;" assignments before "goto ret;" with this change if you want.

Also commit log seems describing the below change not this one ...

I had that change lined up for my next set. But I can send it early.
