Subject: [dpdk-dev] [RFC PATCH 03/17] virtio: Allow starting with link down
Date: Mon,  8 Dec 2014 14:21:42 +0800	[thread overview]
Message-ID: <1418019716-4962-4-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1418019716-4962-1-git-send-email-changchun.ouyang@intel.com>

Starting driver with link down should be ok, it is with every
other driver. So just allow it.
