I think you meant to say that bluetooth is little-endian (mostly!) therefore we
can't use ntoh*. And I agree that the macros already defined in the kernel are
the ones to use. The occasional special field which is not evenly divisible by
eight bits will just have to be handled specially when it comes up (as well as
the occasional opposite-endian field like the bd address).
