Commit 15e9ee6982a4822ce395fd597dd500a61ceafa7c (vhost: enable virtio 1.0)
uses the VIRTIO_F_VERSION_1 macro existing only in newer kernels.
Fixed it by manually defining it for older kernels.

Hi,
I reproduced the issue with 3.9.5 kernel and solved using
Xie, Huawei's idea.
By the way, what is the earlier kernel that DPDK supports?
I tried 3.19 with no luck.
Please let me know if you prefer another way to do it.
Thanks,
Marcel
