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

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.

Before start beaconing cfg80211_reg_can_beacon() verifies the channel
is CAC checked and available calling cfg80211_secondary_chans_ok().
Although the channel is marked NL80211_DFS_AVAILABLE after a CAC
period, ieee80211_monitor_start_xmit() does not allow to inject mgmt
frames on DFS channels causing association failures.

I don't see how this can cause association failures? Please explain.
DFS-capable hostapd doesn't use monitor interfaces with mac80211 any
more.
