Subject: [dpdk-dev] [PATCH 6/8] event/dsw: remove redundant control ring poll
Date: Mon, 9 Mar 2020 07:51:04 +0100	[thread overview]
Message-ID: <20200309065106.23800-7-mattias.ronnblom@ericsson.com> (raw)
In-Reply-To: <20200309065106.23800-1-mattias.ronnblom@ericsson.com>

On dequeue, polling the control ring once is enough.

Fixes: f6257b22e767 ("event/dsw: add load balancing")
