netem with prio hangs on duplicate
hi
i tried the example given on the examples page to
duplicate selected traffic like
tc qdisc add dev eth0 root handle 1: prio
tc qdisc add dev eth0 parent 1:3 handle 3: netem
duplicate 40%
tc filter add dev eth0 protocol ip parent 1:0 prio 3
u32 match ip dst 11.0.2.2 flowid 1:3
when i ping from 11.0.2.2 to this interface my machine
hangs. the same thing works for drop or delay.
i would
