What if I push the calculation into nl80211.c, so it will be only called when the a userspace process requests the station info ? This would mean the calculation is not done at all until someone needs the rate info. > Also, there are duplicate numbers possible, so just the pure bitrate > will _not_ actually be "the typical information" because it's not > specific enough, when debugging, for example, you will probably need to > know whether it's short-gi or not. Don't you think the normal nl80211 use will just be a display of "how fast are we doing at the moment" ? Most applications don't even need to set a rate, they just want to show the user some feedback. Henning
