[dpdk-stable] patch 'ipc: fix send error handling' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/14/19. 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.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/6c4a669bdfc38dd115f5cfe84b03da58770bfda0

Thanks.

Kevin Traynor

Subject: [PATCH] ipc: fix send error handling

[ upstream commit 535113907f23134375b18f40b6642a963ec50141 ]

According to manpage, ENOBUFS error indicates that either the
input or the output queue is full. This should be considered
an error, but it is treated as an "ignore" condition. Fix the
code to report an error instead.

Fixes: bacaa2754017 ("eal: add channel for multi-process communication")
