cxgb3: fix link flap
The driver is expected to report that the link is up when the phy Rx signal is established and the mac has not detected a link fault. The code is however broken, the driver does not check the link fault status when the phy link status changes. The link fault status being checked within a short period of time, it leads to link up/link down events. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S.
