[dpdk-stable] patch 'net/bnxt: fix unconditional wait in link update' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/04/19. 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/052a49557654602d4a3567c81cb761813a6cf4c7

Thanks.

Subject: [PATCH] net/bnxt: fix unconditional wait in link update

[ upstream commit 0a44537589454a9aba3e9ad392218ad433fbf529 ]

There is an unconditional delay in link update op.
Fixed it to wait only if wait for request completion is set.

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