If anyone has any objections, please let me know. ------------------ From: Brett Creeley [ Upstream commit 7678e69079c10b2fb10977f28f44ddb22971ea5b ] 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.
