[dpdk-dev] [PATCH] net/mlx5: fix VLAN inner type matching on DR/DV

[Xiaoyu Min <jackmin@mellanox.com>]

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
