Subject: [dpdk-dev] [PATCH v3 2/5] net/virtio: use simple path for Tx even if Rx mergeable
Date: Thu,  7 Jun 2018 11:26:13 +0200	[thread overview]
Message-ID: <20180607092616.27720-3-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20180607092616.27720-1-maxime.coquelin@redhat.com>

Having Rx mergeable buffers feature enabled should not be
a reason to not use Tx simple path.
