[LARTC] Filtering ACK bits smaller than 64 bytes

Hi there

I want to add a filter for all ACK bits smaller than 64 bytes for a
specific ip destination, but I get RTNETLINK answers: invalid argument.
Any idea what is wrong with the filter below:


tc filter add dev eth1 parent 1:0 prio 1 u32 \
        match ip dst 196.44.35.53 \
        match ip protocol 6 0xff \
        match u8 0x05 0x0f at 0 \
        match u16 0x0000 0xffc0 at 2 \
        match u8 0x10 0xff at 33 \
        flowid 1:20

Thanks,
