Hi,
with a Tomasz suggestions I tried with the setup below but it appears at the
same place, the same error.
RTNETLINK answers: File exists
We have an error talking to the kernel
Is there any other way?

maybe everything that has to do with massive filtering (maybe not

192.168.0.0/16 hashkey mask 0x000000ff at 12 link 2:
change to:
tc filter add dev eth0 protocol ip parent 1: u32 match ip dst 192.168.0.0/24
hashkey mask 0x000000ff at 16 link 2:

add hiere:
echo tc filter add dev eth0 protocol ip parent 1:2 u32 ht 2:$hexi: match
ip dst 192.168.$j.$i flowid 1:3
and show us results.
