Why not use a comparison function which knows how to compare just the
manufacturer's id fields? Or define a function which masks a mac address
to return the id fields and zeros everywhere else (so you can then use
the "normal" comparison functions)?
Defining a new type to allow this masking and comparison seems more than
necessary (which, if this argument holds up, would make it undesirable).
We can still define functional indices so that a table lookup will be
fast in any case.
