[RFC v2 4/8] mac80211: mesh non-peer power mode indication in beacons

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



According to IEEE80211s standard a mesh STA shall indicate itsnon-peer
mesh power mode with the Power Management field in the FrameControl
field and the Mesh Power Save Level field in the MeshCapability field
in Beacon and Probe Response frames.
