This patch adds more functionality to the link\nstatus management code by enabling/disabling the port per-cpu\ninterrupts, and the port itself. The queues are now stopped as well, and\nthe netif carrier helpers are called.\n\nSigned-off-by: Antoine Tenart \n---\n drivers/net/ethernet/marvell/mvpp2.c | 11 +++++++++++\n 1 file changed, 11 insertions(+)","diff":"diff --git a/drivers/net/ethernet/marvell/mvpp2.c b/drivers/net/ethernet/marvell/mvpp2.c\nindex 9c0c81e68d55..09cad32734f3 100644\n--- a/drivers/net/ethernet/marvell/mvpp2.c\n+++ b/drivers/net/ethernet/marvell/mvpp2.c\n@@ -5777,14 +5777,25 @@ static void mvpp2_link_event(struct net_device *dev)\n \t\t\tval |= (MVPP2_GMAC_FORCE_LINK_PASS |\n \t\t\t\tMVPP2_GMAC_FORCE_LINK_DOWN);\n \t\t\twritel(val, port->base + MVPP2_GMAC_AUTONEG_CONFIG);\n+\n+\t\t\tmvpp2_interrupts_enable(port);\n+\t\t\tmvpp2_port_enable(port);\n+\n \t\t\tmvpp2_egress_enable(port);\n \t\t\tmvpp2_ingress_enable(port);\n+\t\t\tnetif_carrier_on(dev);\n+\t\t\tnetif_tx_wake_all_queues(dev);\n \t\t} else {\n \t\t\tport->duplex = -1;\n \t\t\tport->speed = 0;\n \n+\t\t\tnetif_tx_stop_all_queues(dev);\n+\t\t\tnetif_carrier_off(dev);\n \t\t\tmvpp2_ingress_disable(port);\n \t\t\tmvpp2_egress_disable(port);\n+\n+\t\t\tmvpp2_port_disable(port);\n+\t\t\tmvpp2_interrupts_disable(port);\n \t\t}\n \n \t\tphy_print_status(phydev);\n","prefixes":["net-next","v4","06/13"]}
