> The rte_flow_item_vlan has the inner_type, which is missing on DR/DV flow
> engine.
> 
> By adding this support, the example testpmd commands could be:
> 
>  - matching all vlan traffic with id 2:
> 
>  testpmd> flow create 0 ingress pattern eth / vlan vid is 2 / end
>           actions queue index 2 / end
> 
>  - matching all ipv4 traffic in vlan with id 2:
> 
>  testpmd> flow create 0 ingress pattern eth / vlan vid is 2
>           inner_type is 0x0800 / end actions queue index 2 / end
