Ok, the problem seems to come from the fact that rt2800 doesn't register a per channel max power to mac80211. Luis, with rt2800 we are not really able to provide an accurate max tx power :( so, can we restore the previous behavior in reg.c? Or maybe do something like if (chan->max_reg_power) chan->max_power = min(chan->max_power, chan->max_reg_power); Tobias, does that work for you as well?
