Currently, all drivers depend on the bool CONFIG_NET_SWITCHDEV, but only
the drivers that call some sort of function exported by the bridge, like
br_vlan_enabled() or whatever, have an extra dependency on CONFIG_BRIDGE.
Since the blamed commit, all switchdev drivers have a functional
dependency upon switchdev_bridge_port_{,un}offload(), which is a pair of
functions exported by the bridge module and not by the bridge-independent
part of CONFIG_NET_SWITCHDEV.
Problems appear when we have:
CONFIG_BRIDGE=m
CONFIG_NET_SWITCHDEV=y
CONFIG_TI_CPSW_SWITCHDEV=y
because cpsw, am65_cpsw and sparx5 will then be built-in but they will
call a symbol exported by a loadable module. This is not possible and
will result in the following build error:
drivers/net/ethernet/ti/cpsw_new.o: in function `cpsw_netdevice_event':
drivers/net/ethernet/ti/cpsw_new.c:1520: undefined reference to
`switchdev_bridge_port_offload'
drivers/net/ethernet/ti/cpsw_new.c:1537: undefined reference to
`switchdev_bridge_port_unoffload'
As mentioned, the other switchdev drivers don't suffer from this because
switchdev_bridge_port_offload() is not the first symbol exported by the
bridge that they are calling, so they already needed to deal with this
in the same way.
