[dpdk-stable] patch 'ethdev: fix errno to have 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] ethdev: fix errno to have positive value

[ backported from upstream commit 8e0c8dcf3507ae812f1abcd5247617917f131dae ]

rte_errno should be set to positive value from errno.h plus
few RTE-specific values.

Fixes: 4fb7e803eb1a ("ethdev: add Tx preparation")
Fixes: 439a90b5f2a7 ("ethdev: reorder inline functions")
