[dts] [PATCH V1] fix vxlan failed case

[Liu, Yong]

Thanks for clear this.  
There's one open discussion for vector mode switch in DTS.
One option is use testpmd parameter "enable-rx-cksum". It work on ixgbe and i40e, but this method maybe invalid in later release.
Another option is just like patch,  we switch between vector and scatter pmd by configuration file. Between the switch, it will take long time for recompile dpdk.
There's another way is that we build different kinds of testpmd applications like vector/legacy/scatter. It can skip build between switch modes.

Marvin,
