Hi,
That's a very good diagram!

Resuming the thread, Sven said that adding a qdisc to wlan0-1 makes no
sense. I don't understand completely why, but i guess that once bat0
manages wlan0-1, the latter can't work anymore at IP layer, right?

So i've done some tests with bat0. I realized that maybe when i had
applied a SFQ qdisc to bat0, the bottleneck was still on wlan0-1, and
for that reasons packets were dropped on wlan0-1. Then using a HTB qdisc
i limited bat0 rate to a minor value than the wlan0-1 actual output
rate, and added some classes inside with SFQ. This way i could see
dropped packets at bat0 and SFQ working as expected (and no dropped
packets at wlan0-1). However, for this configuration to work, the limit
value rate for bat0 has to be smaller than the output rate of wlan0-1,
but this value is not fixed in a wireless link. I don't know if it's
possible to use another configuration in which it's not necessary to set
a fixed limit value to allow bat0 to control the bottleneck.

Regards

Gabriel
