patch 'net/bnxt: cleanup MTU setting' 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/44e391b5c233943c7a96c9fc11e87cafb8e28e55

Thanks.

Kevin

Subject: [PATCH] net/bnxt: cleanup MTU setting

[ upstream commit 89670e3b0f852615c29c510d5f6c04d147675c7e ]

Minor cleanup in bnxt_mtu_set_op() to move pre-mature
setting of jumbo flag post mtu check and remove
a redundant mtu set operation from rxq vnic configs.

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