The reason we at Atheros were considering it was a possible way to
communicate between two different subsystems, in our case Bluetooth
and 802.11. While it is technically possible to use netlink for such
purposes it introduces a layer of complexity which can be avoided by
just using direct exported routines, and by coordinating between the
two subsystems you need communication with.

So, the real question I think is why do you need a rigid API ? If
there is a good need, perhaps its a good idea, but so far I guess no
one simply has come up with one.
