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.

This option causes debugging code to be compiled into the

mlx4_core driver. The output can be turned on via the
|
|
debug_level module parameter (which can also be set after
|
|
the driver is loaded through sysfs).
