Subject: [PATCH 076/104] mtk: hostapd: Fix chan_switch to usable DFS channel
fail due to ACS
Step and issue:
1. Enable ACS in hostapd config;
2. Bootup and then use hostapd_cli cmd switch channel to a DFS channel;
3. Will do ACS again, and no work on channel specified in step 2.
Root cause:
When need do DFS-CAC, hostapd will do intf disable, then set the new
channel into running config settings, and finally enable intf;
In the test case, new DFS channel is set to runnint config settings, but
another param "acs" is still 1 (enable), caused the ACS running when
intf enabled.
Solution:
In the hostapd_switch_channel_fallback, need to disable acs if channel
is valid.
