patch 'net/txgbe: fix default signal quality value for KX/KX4' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=e7149d390bde6ed9db0ecb32883cce1b34a49ba1

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 7211175417d4f6a7b03a0e7e7355dc62fced8512 ]

On old firmware versions, the default value of signal quality(TX_EQ) is
configured by the driver. Fix it for KX/KX4 mode.

Fixes: 01c3cf5c85a7 ("net/txgbe: add autoneg control read and write")
