And why doesn't this work? (I send all port 80 to 1.2.3.4 to class 14
/before/ I send the rest to classid 13):

$TC filter add dev ${DEV_IFB} parent 1:0 prio 2 protocol ip u32 \
  match ip protocol 0x6 0xff \
  match ip dport 80 0xffff \
  match ip dst 1.2.3.4/32 \
  classid 1:14

$TC filter add dev ${DEV_IFB} parent 1:0 prio 2 protocol ip u32 \
  match ip protocol 0x6 0xff \
  match ip dport 80 0xffff \
  classid 1:13

Any ideas?

Ok, thnx. That's of course a solution, but I just wondered if this were
possible with u32...
