Hi,

FYI, your patch has been queued to stable release 19.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/12/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/831b94f05dbe2fafb96e999ba8119ab76150b5a7

Thanks.

Subject: [PATCH] net/bnxt: fix check for PTP support in FW

[ upstream commit a642112c91246b035dfa6d6f5bc52b0603c44952 ]

On Thor, driver must use HWRM to access the timestamp information.
Driver should not advertise PTP support to application
if PTP information is not available via HWRM commands.

Fixes: 6cbd89f9f3d8 ("net/bnxt: support PTP for Thor")
