Anyone tried ath10k AP with 40Mhz operation?

[Ben Greear <greearb@candelatech.com>]

I'm trying this hostapd config file.  Beacons seem OK, and station
associates.  Station puts DHCP Discover on the air (using 20Mhz according
to wireshark).  AP reads this, and thinks it is sending a DHCP response back,
but sniffer never shows DHCP response on the air.

Kernel is 4.0.4+, ath10k firmware is CT firmware, 10.1.467 based.

I am curious if anyone else has tried to do this?

Thanks,
Ben
