Subject: [PATCH] hostapd: Fix channel switch on 6g
|
|
|
|
Below cmd does not return fail, but fails to update beacon.
|
|
Center frequency used in command is not valid for 80M bandwidth.
|
|
|
|
hostapd_cli -i wlan0 chan_switch 5 6315 sec_channel_offset=1
|
|
center_freq1=6345 bandwidth=80 he
|
|
|
|
This patch adds condition check to validate the center frequency.
