Subject: [dpdk-dev] [PATCH] net/virtio: init MTU in case no control channel
Date: Wed, 25 Oct 2017 20:09:06 -0700 [thread overview]
Message-ID: <1508987346-68173-1-git-send-email-wangzhike@jd.com> (raw)
The max_mtu is kept as zero in case no CRTL channel, which leads
to failure when calling virtio_mtu_set().
