How can I use 5Ghz FTM AP mode Wi-Fi Location on Intel 8260 based on 802.11mc

[swkim]

Hello !

I have been working and testing FTM function using Iwlwifi on intel 8260.

Now, I used below
* iwlwifi driver - core30 backporting, intel firmware version 31.
and iw 4.9 version (already i patched patch -p1 < bef149ad0c1b8c8f.txt)

I have tested AP mode on 2.4GHz (on devices driven by iwlmvm), it is OK.

But, I cannot use 5Ghz band as FTM Respondor.

How can I use 5Ghz band with AP mode?

-Basic information

* 0S : Debian GNU/Linux 9

* Kernel : Linux version 4.4.194

* Enable 802.11mc FTM on Intel 8260

iwlwifi :   switch to release/LinuxCore30

intel fw : iwlwifi-8000C-31.ucode

wget https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/tree/iwlwifi-8000C-31.ucode
