perfect, thanks. But still there is something which I don't get.

The split you mentioned about the functionality is for me being a
coordinator (IEEE spec) or pan coordinator (IEEE spec) which has the
additional functionality of "send beacons, manage assocs, act as
relay".
So a coordinator (iftype) is a pan coordinator (IEEE spec) and a node
(iftype) is a coordinator (IEEE spec), but _only_ when it's
associated, before it is just a manually setup mesh node?

I hope it's clear when meaning iftype and when meaning IEEE spec, but
for the manual setup thing (node iftype) there is no IEEE spec,
although it is legal to do it in my opinion.

Thanks.
