If I understand the logic behind the power increase through chain combining properly, this value only describes the worst-case (wrt. regulatory compliance) upper limit of tx power, whereas in practice the measured combined power output will be much lower than that due to signal/phase differences. Regulatory compliance is already properly tested on all devices with the truncated value 9, so I don't think that we need to be even more conservative and round up here. - Felix -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
