tc filter выдает ошибку

[Nicholas <nicholas@networkgate.us>]

Команда "tc filter..." выдает ошибку, с любыми аргументами.
Почему?
Пример:
debian# tc filter add dev eth0 parent 10:0 protocol ip prio 1 u32 match 
ip dst 192.168.1.13/24 flowid 10:20
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
debian# tc filter add dev eth0 parent 1:0 protocol ip prio 5 handle 1: 
u32 divisor 1
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
