Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/25/23. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/de481ff9ddb85bddac2834cbdae53280a119aa3d

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix link state change interrupt config

[ upstream commit 60653f4a25bd87a32bc148461f32566af997da8b ]

When getting the device's info via bnxt_dev_info_get_op(), the device
enables interrupts on link state changes because of the following line:

  eth_dev->data->dev_conf.intr_conf.lsc = 1;

Enabling this mode might not be wanted by the user.

The flag RTE_ETH_DEV_INTR_LSC can be used to inform the above
application that LSC interrupts are supported. Thus, checking this flag,
the user can decide whether or not to enable these interrupts.

Since there is no reason for a function meant to display config to
actually modify it, remove this line. In addition, raise the dev_flag
associated with this state on the device's initialization to show the
device supports link state change interrupts.

Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")
