[dts] [PATCH V1] fix vxlan failed case

[Xu, HuilongX]

Hi yong,
I think, dts framework should compile many times for different compile switch.
Then case should  choose different dpdk APP for test.
Could you merge this patch fist, and we can submit a new patch for dts framework compile many dpdk with different compile switch.
Thanks a lot
