Please either use ipt action and netfilter fwmarker for this activity or
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

cheers,
