This WPA_KEY_MGMT_* bitmap is implementation specific and that itself
would not be much of an issue to extend, but the PASN AKM suite selector
itself is waiting for ANA assignment and as such, does not look ready to
be applied yet. Similarly, I'm not yet convinced that the crypto design
is yet finalized, so this patch as whole looks a bit too early at this
point in time.
