Do you mean to say that the handle of the root _qdisc_ is 11:0?
(I could not find that configuration command in your email)

Is the traffic that should match the filter going through the qdisc at all?
(you can check the qdisc counters)

If it is, then maybe there is another filter (with higher priority?)
that catches the packets earlier. Can it be the case?

No, none of this was the cause. I think that was fw filter. I've changed
to u32 and everything works fine:

Before:
#tc filter add dev eth1 parent 11:0 protocol ip handle 1 fw classid 11:2

After:
#tc filter add dev eth1 parent 11:0 protocol ip prio 1 u32 match ip dst
192.168.10.0/24 match mark 1 0xffff flowid 11:2

Cheers,
