[PATCH net-next 02/16] mlxsw: spectrum: Check bridge flags during prepare phase

[Florian Fainelli]

In preparation for getting rid of switchdev_port_attr_get(), have mlxsw
check for the bridge flags being set through switchdev_port_attr_set()
with the SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS attribute identifier.
