In linux kernel since version 3.10 (release Date: 2013-06-30)  
This enables VOP (Virtio over PCIe) Driver support for the Intel
Many Integrated Core (MIC) family of PCIe form factor coprocessor
devices. The VOP driver allows virtio drivers, e.g. net, console
and block drivers, on the card connect to user space virtio
devices on the host.

If you are building a host kernel with an Intel MIC device then
say M (recommended) or Y, else say N. If unsure say N.

More information about the Intel MIC family as well as the Linux
OS and tools for MIC to use with this driver are available from
