Not necessarily, but some information about why this is needed would be good. I guess since this has no way of using something like 11v this really is the only chance. Note that you'll need to add a feature capability flag for this - many drivers, even ones based on mac80211, will not be able to implement this properly so relying only on the presence of the callback will not work properly. johannes -- 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
