4Subject: [PATCH] hostapd: mtk: Add the broadcast destination address of Probe
5 Response frame on 6 GHz
6
7According to IEEE 802.11ax 26.17.2.3.2,
8if a 6 GHz AP receives a Probe Request frame and responds with a Probe Response frame,
9the Address 1 field of the Probe Response frame shall be set to the broadcast address,
10unless the AP is not indicating its actual SSID in the SSID element of its Beacon frames.
11
12Without this, hostapd fill the Address 1 feild of the Probe Response frame
13with the source address from Probe Request frame on 6 GHz.
14Fix this to use broadcast address instead.
