From: Brett Creeley The current check will fail if SR-IOV is not initialized for the physical function; this is because is_physfn is 0 if sriov_init() isn't run or fails. Change the check that prevents getting the link down count to use is_virtfn instead so that VFs don't get this functionality, which was the original intent.
