Subject: [dts] [PATCH v2 3/4] framework: reorganize DUT and Tester port initialize sequence
Date: Wed,  4 Feb 2015 14:43:33 +0800	[thread overview]
Message-ID: <1423032214-19856-4-git-send-email-yong.liu@intel.com> (raw)
In-Reply-To: <1423032214-19856-1-git-send-email-yong.liu@intel.com>

DUT port initialization sequence: scan,restore,rescan,load config
Test port initialization sequence: modprobe, interface up
Separate restore interface function from DUT and Tester.
