[dpdk-stable] patch 'net/ena: fix errno to positive value' has been queued to LTS release 17.11.6

[Yongseok Koh <yskoh@mellanox.com>]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

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")
