Please either use ipt action and netfilter fwmarker for this activity or
Sorry. There are only unsuccessful attempt to popularize my working solution.
Really I just use "#define tc_index mark" (in skbuff.h or sch_ingress.c) or
something like this:

create a new action.
If you choose the later (example because you want to dynamically compute
the mark), look at net/sched/act_simple.c to start from and i can help
you if you have any questions.
If you want to use ipt action, the syntax would be something like:
---
tc qdisc add dev XXX ingress
tc filter add dev XXX parent ffff: protocol ip prio 5 \
u32 blah bleh \
flowid 1:12 action ipt -j mark --set-mark 13
Yes, I do so. But there are simple:
---
if [[ $[TC_INDEX2MARK] == 0 ]] ; then
c=${c//action ipt -j MARK --set-mark /flowid :}
fi
$c
