[dpdk-stable] patch 'net/bnxt: replace memory barrier for doorbell response' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/19. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/b2bfe186b0770637d2fdff4f5357bce8950b816c

Thanks.

Kevin.

Subject: [PATCH] net/bnxt: replace memory barrier for doorbell response

[ upstream commit 21ecbde99b2f0772d36eef8276a686f3135e5de9 ]

To read the doorbell response, which is held in the host CIO memory,
rte_cio_rmb is sufficient.

Fixes: 804e746c7b73 ("net/bnxt: add hardware resource manager init code")
