patch 'net/bnxt: allow Tx only or Rx only' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/30/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/17d0b87c871a9b6ccfc0e9e00b5db36455b2a6bf

Thanks.

Kevin

Subject: [PATCH] net/bnxt: allow Tx only or Rx only

[ upstream commit 8b7e58a791ef7747266b77ed433f5d03a6abaad7 ]

Currently, we fail the init/probe of PMD if eth_dev->data->nb_tx_queues
or eth_dev->data->nb_rx_queues is 0. We are removing this check.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
