developer52278a12023-03-02 20:22:29 +08004Subject: [PATCH 14/16] hostapd: mtk: Add the broadcast destination address of
developerb8853042023-02-17 11:50:45 +08005 Probe Response frame on 6 GHz
developer1c2c7d42023-01-18 18:20:58 +08006
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.
