Subject: [net-next-2.6 PATCH 4/5] igb: correct link test not being run when
	link is down

From: Alexander Duyck <alexander.h.duyck@...el.com>

The igb online link test was always reporting pass because instead of
checking for if_running it was checking for netif_carrier_ok.

This change corrects the test so that it is run if the interface is running
instead of checking for netif carrier ok.
