[dpdk-stable] patch 'net/bnx2x: fix reset of scan FP flag' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnx2x: fix reset of scan FP flag

[ upstream commit d836d5efb93505ad86f72c0fcfb0f650858b96ac ]

The fastpath task queue handler resets the fastpath scan flag
unconditionally, this patch changes that to reset the flag
only if it was set.

Fixes: 08a6e472c3d7 ("net/bnx2x: fix packet drop")
