* Performance
similar to KNI, this solution would use one or more kthreads to
- send/receive packets from user space DPDK applications, which has little
+ send/receive packets to/from user space DPDK applications, which has little
impact on user space polling thread (except that it might enter into kernel
space to wake up those kthreads if necessary).

This command runs testpmd with two ports, one physical NIC to communicate
This is used to negotiate VIRTIO_NET_F_GUEST_TSO4 and
VIRTIO_NET_F_GUEST_TSO6 feature so that large packets from kernel can be
- transmitted DPDK application and further TSOed by physical NIC.
