Uwe Kleine-König a264b981f2 net/fec: Don't let ndo_start_xmit return NETDEV_TX_BUSY without link ... Don't test for having link and let hardware deal with this situation. Without this patch I see a machine running an -rt patched Linux being stuck in sch_direct_xmit when it looses link while there is still a packet to be sent. In this case the fec_enet_start_xmit routine returned NETDEV_TX_BUSY which makes the network stack reschedule the packet and so sch_direct_xmit calls fec_enet_start_xmit again. I failed to reproduce a complete hang without -rt, but I think the problem exists there, too. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: David S.
