Hello every:
    When I read the DPDK document, I got a problem that I can't get the descriptor of a NIC.(http://dpdk.org/doc/guides/nics/virtio.html)
    I want use virtio with kni vhost back end, but I can't find the file /sys/class/net/vEth0/sock_en and /sys/class/net/vEth0/sock_fd.
    
 [root at 192.168.100.40]# cd vEth0/
[root at 192.168.100.40]# ls
addr_assign_type  addr_len   carrier  dev_port  duplex    flags    ifindex  link_mode  operstate     power   speed       subsystem     type
address           broadcast  dev_id   dormant   features  ifalias  iflink   mtu        phys_port_id  queues  statistics  tx_queue_len  uevent
    I use CentOS6.5 with kernel 2.6.32-573.7.1.el6.x86_64.
