[dpdk-stable] patch 'net/ice: fix unchecked Tx cleanup error' has been queued to stable release 19.11.1

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 02/19/20. 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/ice: fix unchecked Tx cleanup error

[ upstream commit fe38133c42d846613a41beff49ab0e1b9a3e0e61 ]

Coverity complains of unchecked return value warning of
ice_xmit_cleanup, while this cleanup is opportunistic and will not cause
problems if it fails. So instead of checking the return value of
ice_xmit_cleanup and return in case of cleanup failure, we directly cast
it to void function to make the Coverity happy.

Coverity issue: 353623
Fixes: 17c7d0f9d6a4 ("net/ice: support basic Rx/Tx")
