[PATCH] hostapd: send own Neighbor Report only if specific Measurement Request

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

 



Every Neighbor Report that matches the requested SSID is sent in the
Neighbor Report Response, including our own report. According to standard
IEEE 802.11-2020 (11.10.10.3), the self report should not be included in
the response unless the request includes a LCI Measurement Request or a
Location Civic Measurement Request.
