Seems my silly mistake, i used wrong option in skbedit (first which i seen in 
example). 
Thanks to Intel guys, now it is possible also by this way:

tc qdisc del dev eth2.10 root
tc qdisc add dev eth2.10 root handle 1: prio
/sbin/tc filter add dev eth2.10 parent 1:0 protocol all u32 match u32 0 0 
action skbedit priority 3

So it is possible now to do 802.1p marking on router(not bridge), by u32 
filter or whatever.

tc qdisc del dev eth2.10 root
tc qdisc add dev eth2.10 root handle 1: prio
/sbin/tc filter add dev eth2.10 parent 1:0 protocol all u32 match u32 0 0 
action skbedit priority 3

Like this it works


And thanks again, i am really impressed by opensource initiatives of Intel, 
and quality/performance/cost of their network products.
