If you have runtime control of this, I suggest making it default to on,
like mthca does with:

	config INFINIBAND_MTHCA_DEBUG
		bool "Verbose debugging output" if EMBEDDED
		depends on INFINIBAND_MTHCA
		default y

otherwise distros will leave the option off and it becomes a pain to
debug problems because you force users to do compiles.
