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.

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
