Subject: [dpdk-dev] [PATCH 3/4] examples/vhost: use a new API to query remaining ring space
Date: Mon, 6 Sep 2021 20:48:36 +0000 [thread overview]
Message-ID: <20210906204837.112466-4-wenwux.ma@intel.com> (raw)
In-Reply-To: <20210906204837.112466-1-wenwux.ma@intel.com>
A new API for querying the remaining descriptor ring capacity
is available, so we use the new one instead of the old one.
