This is wrong. IEEE priorities are opposite of IETF priorities (as used by
skb->prio).
Unless you install a prio qdisc and rewrite the priomap, you are screwed.
So you should do opposite mapping, i.e something along the lines of
VLAN_TCI priority (0..7) to skb->priority (15..8) i,e

skb->priority = 15 - vlan_TCI;
