Why are some of these commented out?  Since they're apparently exposed
to user-space you can't insert them later.

We are working to define a next version of netlink API for the stack
right now. But taking into account, that iz tool & upper layers of
stack will be the only users of this API at least for next year, and
IEEE802.15.4 spec is evolving, it is probably not necessary to come up
with a very final version.

Kind regards,
Maxim
