I don't know if we really want to add one sub-option for each selftest
subsystem, that would be quite a lot.

However, we should properly enable/disable selftest subsystems
depending on the availability of the necessary dependencies. For
example, if numactl is enabled, then we enable the network-related
selftests, otherwise we disable them.

Best regards,

Thomas
