It is because of a recent patch http://patchwork.dpdk.org/patch/36068/

If you don't care about VLAN action, just remove that action all together
and check the correctness of your code.
If all of them are going to q0 (and assuming isolation mode is not
enabled), then it is most likely because packets don't match any of the
rte_flow rules you created.
