We have DFS working on Fedora with CT firmware and driver.
One thing, you have to enable .11d and .11h features for DFS to be enabled.
Also, we over-ride the ath10k firmware country-code using the module-param
so that the entire system has the same country-code:
# You do not need most of this below, and possibly none of it...I'm not
# how much the country-code for the NIC matters.
[root@ben-ota-1 ~]# cat /etc/modprobe.d/ath10k.conf
# LEAVE-ME-BE
# MAC, WMI, HTC
#options ath10k_core debug_mask=0xc0000036
# MAC
options ath10k_core debug_mask=0xc0000030
# htt tx dump
# options ath10k_core debug_mask=0xc00000b0
# Quiet
#options ath10k_core debug_mask=0xc0000000
options ath10k_core nohwcrypt=1
options ath10k_core num_vdevs_ct=64
options ath10k_core num_peers_ct=128
options ath10k_core num_msdu_desc_ct=680
#options ath10k_core num_rate_ctrl_objs_ct=20
options ath10k_core override_eeprom_regdomain=840
And, does this work w/out CT firmware and driver? If so, might be some issue
with my code, but again, it seems to work for us.
Thanks,
Ben

I am trying to put an AP on a DFS channel (52).
I am using a TP-Link Archer C7 v2 with LEDE Reboot r1462 / LuCI Master
(git-16.237.78341-d5f8c9b) and the ath10k CT firmware/driver.
Hostapd will not start the AP because of some problem with DFS.
Does anyone have this working ?
