| Subject: [PATCH 14/29] hostapd: mtk: Add the broadcast destination address of |
| Probe Response frame on 6 GHz |
| |
| According to IEEE 802.11ax 26.17.2.3.2, |
| if a 6 GHz AP receives a Probe Request frame and responds with a Probe Response frame, |
| the Address 1 field of the Probe Response frame shall be set to the broadcast address, |
| unless the AP is not indicating its actual SSID in the SSID element of its Beacon frames. |
| |
| Without this, hostapd fill the Address 1 feild of the Probe Response frame |
| with the source address from Probe Request frame on 6 GHz. |
| Fix this to use broadcast address instead. |
