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

[Zhimin Huang]

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.
so we add parameter "enable-hw-vlan" in testpmd,there is no gap in avx2 and avx512 to test vlan strip.

 1. Start testpmd with mac forward mode::
