[dts][PATCH V1] vf_vlan/vf_vlan_rx:modify code to adapt avx2 and avx512 on vlan offload

[Zhimin Huang]

base on dts commit 92e12676d29341695d86ef8ee8e36d4014d56e98,missing
vf_vlan_rx test case modification.

add parameter "--enable-hw-vlan" in testpmd.
the dpdk commit 5cbfb386aa3f4c49b3cd9579e4e928cc5ab08d35 fixed avx2 not support this parameter.
the avx2 behavior is not appropriate,it has gap between avx2 and avx512,
this feature will be implemetned in the future.
so we add parameter "enable-hw-vlan" in testpmd,there is no gap in avx2 and avx512 to test vlan strip.
