Hi,
First thing: Don't reply to random messages when you actually want to start a

Ok.
We are doing some tests with Traffic Control (tc) in routers with
Openwrt running batman-adv, want to be able to share the bandwidth with
some degree of fairness between users, so we think that SFQ could help,
differentiating the flows depending on ip addresses and ports.
The problem is that when adding the SFQ qdisc to the wireless interface
managed by batman it doesn't work as expected. We tested the SFQ in
other configurations and it worked fine, in full queues, the dropped
packets affected the big flows, allowing the others to pass, but in the
interface managed by batman-adv when packets are dropped, the result
affects all flows almost equally. We thought this could be related with
the bridge we use to connect the batman with the non-batman interfaces,
but in a wireless Acces Point bridged to bat0 it also worked fine. Maybe
it's related with the way bat0 works with it's managed interface? We'd
appreciate any advices. Thanks in advance!
Why do you add the sfq qdisc to the wireless device instead to the bat0
device? It doesn't really makes sense to me.
I also tryed with bat0, but the packets continued to dropp on the
wireless device, not in bat0, so i thought that the qdisc of bat0 was
not being used. Anyway, i'll try again.
Also your statement about "batman-adv bridged with non-batman-adv" doesn't
work, but "batman-adv bridged with non-batman-adv interface" works statement
is slightly irritating. Please explain it a little bit more verbose to help us
understand what is the difference.
Sorry for the bad explanation,what i wanted to say is:
We have a bridge with bat0, eth0 and wlan0 attached. wlan0 is in ap
mode. There's another wireless interface, wlan0-1 in ad-hoc mode,
managed by bat0. When SFQ qdisc is applied to wlan0, it works as
expected. When it's aplied to wlan0-1, it doesn't. In both cases there's
a bridge involved, that´s what i was trying to point. I hope now it's
more clear.
Best regards
Gabriel
