Get wireless stations

List wireless stations (clients) associated with the given node, access point, or wireless domain. For a node, stations last collected from the node acting as wireless controller or standalone access point are returned (empty list for other nodes). For an access point, stations are taken from its controller node or read from the domain's controller bridge. For a wireless domain, stations reported by the controller bridge (if configured) and by all wireless controller nodes in the domain are returned, excluding stations associated with access points the caller has no read access to. Bridge-backed requests query the external controller and may take noticeable time.
