Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/741a4e8fca9cadcb5b3fbb7fdaeed139577d8792

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] net/bnxt: prevent device access in error state

[ upstream commit c967098a4c0aafa0cb244ab9423fdea3d943d1ab ]

Driver should prevent any DMA with the device when it
detects an error. When firmware is in fatal state,
stop tx/rx by assigning them to dummy functions.

Fixes: be14720def9c ("net/bnxt: support FW reset")
Fixes: 9d0cbaecc91a ("net/bnxt: support periodic FW health monitoring")
