Subject: [dts] [DTS][PATCH 2/3] virtio: update vhost user cases
Date: Thu, 21 Jan 2016 14:42:51 +0800	[thread overview]
Message-ID: <1453358572-30310-2-git-send-email-jingguox.fu@intel.com> (raw)
In-Reply-To: <1453358572-30310-1-git-send-email-jingguox.fu@intel.com>

    1: optimize case
    2: add get rx rate for generator
    3: better way to check vhost.out file
