Re: [PATCH] mac80211: allow mgmt frame transmission on DFS channels

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am not using latest mac80211/hostapd (in particular
compat-wireless-2013-04-16/hostapd-20130807) because I have to port
some personal stuff. In this scenario I was not able to establish an
AP/STA connection on DFS channel. Anyway I will update these packages.
