CPSW switchdev based driver which is operating in dual-emac mode by default, thus working as 2 individual network interfaces. The Switch mode can be enabled by configuring devlink driver parameter "switch_mode" to 1: devlink dev param set platform/48484000.switch \ name switch_mode value 1 cmode runtime This can be done regardless of the state of Port's netdevs - UP/DOWN, but Port's netdev devices have to be UP before joining the bridge to avoid overwriting of bridge configuration as CPSW switch driver completely reloads its configuration when first Port changes its state to UP. When the both interfaces joined the bridge - CPSW switch driver will start marking packets with offload_fwd_mark flag unless "ale_bypass=0". All configuration is implemented via switchdev API and notifiers. Supported: - SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS: BR_MCAST_FLOOD - SWITCHDEV_ATTR_ID_PORT_STP_STATE - SWITCHDEV_OBJ_ID_PORT_VLAN - SWITCHDEV_OBJ_ID_PORT_MDB - SWITCHDEV_OBJ_ID_HOST_MDB Hence CPSW switchdev driver supports: - FDB offloading - MDB offloading - VLAN filtering and offloading - STP Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.
