This is due to the promiscuous mode being cleared by the restart. The mac-fcc already includes code to set the promiscuous mode back during the restart. This patch adds the same handling to mac-fec and mac-scc. Tested with bridge function on MPC885 with FEC. Reported-by: Germain Montoies Signed-off-by: Christophe Leroy Signed-off-by: David S.
