I think the current rate control algorithms do not support dynamic rate selection for multicast/broadcast, so they will end up picking the lowest rate from the basic rate set. Anyway, if you include only a single rate in the basic rate set, that rate will be used for multicast/broadcast frames. - Jouni -- 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
