Subject: [PATCH 3/3] net: move the eth_dev status detection at driver level
Date: Sun,  9 Sep 2012 17:44:02 +0200	[thread overview]
Message-ID: <1347205442-14299-3-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <1347205442-14299-1-git-send-email-plagnioj@jcrosoft.com>

as this is depend on the phy link status

If not phylib used force active
