5G Adaptivity测试fail，添加干扰以后设备未立即响应，依旧有信号传输，干扰强度从-75加强到-67左右设备通过。
解决方案：
1> Change threshold
/vendor/firmware_mnt/image/bdwlan.bin
//2.4G
thr_cca_etsi_ovd_G_0_0 0x0
thr_cca_pri20_G_0_0 0x0
thr_cca_ext20_G_0_0 0x0
thr_cca_ext40_G_0_0 0x0
thr_cca_ext80_G_0_0 0x0
//5G
thr_cca_etsi_ovd_A_0_0 0x1 //enable overridethr_cca_pri20_A_0_0 0x1e //primary 20Mhz
thr_cca_ext20_A_0_0 0x1e //secondary 20Mhz
thr_cca_ext40_A_0_0 0x21 //secondary 40Mhz, 3dB higher than 20Mhz to trigger the same power density level as 20Mhz.
thr_cca_ext80_A_0_0 0x24 //secondary 80Mhz, 3dB higher than 40Mhz
2> Change country code
iw reg set FR
3> disable scan
iwpriv wlan0 setUnitTestCmd 9 2 1 0
