The different power modes of links towards neighbor STA can be read using
iw <dev> station get
-or-
iw <dev> station dump
The different power modes shown are:
- mesh local PS mode
- mesh peer PS mode
- mesh non-peer PS mode
where the local PS mode is "our" mode towards the neighbor, the peer PS mode
is the neighbor's mode towards us, and the non-peer PS mode is the neighbor's
non-peer PS mode as indicated in beacons and management frames.
The local PS mode can be modified for each neighbor using
iw <dev> station set <mac-addr> mesh_power_mode <active|light|deep>
