Module ping 

ping: reachability and path quality, measured over the mesh.

Like manage and peer-repeaters this borrows the attached radio and becomes a node, but it needs no authorization from the far end: an Echo Request is a plain MAC command that every node’s MAC answers on its own. What a ping is for is measuring the path that real traffic will take, so the flags here are the frame’s own shape—MIC size, source form, flood budget, an explicit route, the channel it rides—and they carry through to the wire untouched.
