[OpenWrt-Devel] Status of DFS in OpenWrt -> ath9k

[Martin Garbe]

Hi,

for me it seems that DFS is broken in current trunk for ath9k.
I use trunk and compiled ar71xx. With the following configuration on a
Ubiquity Nanostation locoM5

---------
config wifi-device 'radio0'
	option type 'mac80211'
	option hwmode '11na'
	option path 'pci0000:00/0000:00:00.0'
	option htmode 'HT20'
	option country 'DE'
	option channel '104'
	option txpower '20'

config wifi-iface
        option device 'radio0'
        option encryption 'none'
        option network 'wifi'
        option mode 'ap'
        option ssid 'OpenWRT'
        option ifname 'wlan0'
---------

All DFS channel attempts fail with
	start_dfs_cac() failed, -1

Full log is as follows:

----------------

I know that I already used DFS channels in March but I am not sure
whether it was with plain trunk or additional own patches.
