Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/22. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/e7f6c7629a40074eb4e04db3393af7453e12af1c

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix check for autoneg enablement

[ upstream commit 7b82c4de0d67719390674215d4580e20459f5b9b ]

HWRM_PORT_PHY_QCFG_OUTPUT response indicates the autoneg speed mask
supported by the FW. While enabling autoneg, driver should also check
the FW advertised PAM4 speeds supported in auto mode which is set
in the HWRM_PORT_PHY_QCFG_OUTPUT response.

Fixes: c23f9ded0391 ("net/bnxt: support 200G PAM4 link")
