After reviewing our mesh test suite, I would vote for disallowing mesh
point addition via iw.  We currently force topologies by 1. turning
auto peering off, 2. waiting for neighbors to be discovered and 3.
controlling peering with 'iw ... station set <MAC address>
plink_action <open|block>'

Thadeu, would this approach work for you?
