Hello,
I am currently using madwifi-dfs r3800, and I am noticing this behaviour.
I build an ap, (outdoor=1, countrycode 380 (italy)) and issue athchan
100-140. I issue ifconfig up and the ath starts looking for radars, as
expected. After the timeout occurs (no radars found) there is no
transmissions at all of beacon. The ath seems dead.
Taking a look at the code and enabling debug, i see
ath_dfs_cac_completed() is called, CHANNEL_DFS_CLEAR is set
(_ath_set_dfs_clear(), row 9631 in file if_ath.c) but after few lines
ath_reset() is called, which apparently clears all flags, including
CHANNEL_DFS_CLEAR, and the beacon doesnt go on air (I get "Invoked a
transmit function before end of DFS channel availability check").

Is that normal? Any hint?
Obviously, re-setting CHANNEL_DFS_CLEAR in ath_reset() only if it was
enabled is easy and it works, but I dont know if that is a correct way
to act..

Thanks in advance,

G.
