The new NET_DEVLINK infrastructure can be a loadable module, but the drivers using it might be built-in, which causes link errors like: drivers/net/built-in.o: In function `mlx4_load_one': :(.text+0x2fbfda): undefined reference to `devlink_port_register' :(.text+0x2fc084): undefined reference to `devlink_port_unregister' drivers/net/built-in.o: In function `mlxsw_sx_port_remove': :(.text+0x33a03a): undefined reference to `devlink_port_type_clear' :(.text+0x33a04e): undefined reference to `devlink_port_unregister' There are multiple ways to avoid this: a) add 'depends on NET_DEVLINK || !NET_DEVLINK' dependencies for each user b) use 'select NET_DEVLINK' from each driver that uses it and hide the symbol in Kconfig. c) make NET_DEVLINK a 'bool' option so we don't have to list it as a dependency, and rely on the APIs to be stubbed out when it is disabled d) use IS_REACHABLE() rather than IS_ENABLED() to check for NET_DEVLINK in include/net/devlink.h This implements a variation of approach a) by adding an intermediate symbol that drivers can depend on, and changes the three drivers using it.
