[dpdk-stable] patch 'net/ena: fix errno to positive value' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/14/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] net/ena: fix errno to positive value

[ upstream commit baeed5f404dd1b049118cfec26a2fd3203671572 ]

The rte_errno shouldn't have assigned negative error codes, so it has
to be fixed.

Fixes: b3fc5a1ae10d ("net/ena: add Tx preparation")
