[dpdk-stable] patch 'test/distributor: fix quitting workers in burst mode' has been queued to stable release 19.11.6

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/30/20. 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] test/distributor: fix quitting workers in burst mode

[ upstream commit f72bff0ec2723b7d7bfc9c655419030b1c8fffad ]

Sending number of packets equal to number of workers isn't enough
to stop all workers in burst version of distributor as more than
one packet can be matched and consumed by a single worker. This way
some of workers might not be awaken from rte_distributor_get_pkt().

This patch fixes it by sending packets one by one. Each sent packet
causes exactly one worker to quit.

Fixes: 775003ad2f96 ("distributor: add new burst-capable library")
