Weird but there is no class 1:1.

Unfortunately that doesn't work either (btw. tc class add ... htb ... -
missed htb).

Now when I'm downloading only on .134 machine I get maks about
20 Kbyte/s - only at beggining in first second I get 40 Kbyte/s which
drops to 20 Kbyte/s...

No drops?

Anyway rest works as I described in previous email... downloading
from linuxRT gives me as much bandwidtch as htb rules allow but
downloading from internet causes only half of bandwidtch to be
used even if rest is not used.

I'm going to try esfq because it seems that wrr doesn't work properly
with 2.4 kernels either (at least statistics shown by tc class are in
most cases zeros for each dynamicly created class).
