Re: [RFC 1/5] cfg80211: export minstrel best rate information through get_station()

Hi all,

I do also agree that the expected throughput [=max_throughput(mac_throughput_rate) * success_probability(max_throughput_rate)] is the value of interest.
For my current power control development I just use those minstrel statistics per client, that are provided via debugfs and parse those values that I am interested.
Maybe it is an alternative option for your development of batman is such a way to use those debugfs statistics, where you have all information, expected throughput included. And once your experimentation shows which subset of those stats is sufficient for a better routing performance, you go for a proper api. Or are you already confident about the expected throughput value is the one and only ?

Greetings Thomas
