Hi all,

According to Dave T=C3=A4ht the= following code disables Airtime Fairness:

for i in /sys/kernel/debug/ieee80211/phy*/*/airtime_f= lags

do
echo 0 > $i
done


Wouldn'= t it be a good idea to ship Lede with ATF baked in, but disabled at default= ? That would allow end-users to easily enable ATF. Since enabling ATF takes= some work, people without the knowledge wouldn't accidentally enable t= his feature and run into possible instability issues. But at the same time,= this would enable tech savvy people to experiment.

There are reports of people running their networks with ATF enable= d for weeks with no issues whatsoever, so if there are instability issues i= t might not be as widespread as one would think. There is an interesting di= scussion going on here:=C2=A0https://bugs.lede-project.org/index.ph= p?do=3Ddetails&task_id=3D368

I'= m curious to your thoughts!
