Accesslist Tx/Rx Limit

Hi,

anyone knows what Accesslist AP TX/Client TX Limit exactly does.

My problem is when doing PCQ on a wireless Interface where there are
accesslist limits set I get strange effects. I see unlimited wireless clients
get limited to the limits set for other wireless clients. This happens when
a limited wireless client uses its bandwith up to the limit.

So I guess Accesslist limits are implemented as an invisible entry
thrown into the htb-tree of the wireless interface ??

Thanks,
Stefan
