Hello, I have started studying DFS support possibilities in ath9k and I have noticed that at the moment AP is not allowed to change channels when it's using beacons. I have found that I can go around it by setting CHAN_MODE_UNDEFINED for this case. Not sure whether we need extra mode for it but to me this is a case when AP is neither fixed nor hopping. --- a/net/mac80211/chan.c +++ b/net/mac80211/chan.c @@ -34,8 +34,11 @@ return CHAN_MODE_HOPPING; } - if (sdata->vif.type == NL80211_IFTYPE_AP && - !sdata->u.ap.beacon) + + /* TODO: CHAN_MODE_FIXED shouldn't be set when + AP is on DFS channel. For now assume always + undefined */ + if (sdata->vif.type == NL80211_IFTYPE_AP) continue; return CHAN_MODE_FIXED; It's also possible to check whether channel is of radar type and set mode undefined for this case. Question is whether it's needed at all. Any comments?
