Add new TX WQE fields for Connect-X5 vlan insertion support, type and vlan_tci, when type = MLX5_ETH_WQE_INSERT_VLAN the HW will insert the vlan and prio fields (vlan_tci) to the packet. Those bits and the inline header fields are mutually exclusive, and valid only when: MLX5_CAP_ETH(mdev, wqe_inline_mode) == MLX5_CAP_INLINE_MODE_NOT_REQUIRED and MLX5_CAP_ETH(mdev, wqe_vlan_insert), who will be set in ConnectX-5 and later HW generations.
