[dpdk-stable] patch 'net/bnx2x: fix link events polling for SRIOV' 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/7e669a190758b490ab017739ccc2efb66680b256

Thanks.

Kevin Traynor

Subject: [PATCH] net/bnx2x: fix link events polling for SRIOV

[ upstream commit 3423521ba06791211264cae9de196c99424062be ]

We do not need to schedule periodic poll for slowpath link events
for SRIOV. The link events are handled by the PF driver.

Fixes: 6041aa619f9a ("net/bnx2x: fix poll link status")
