This enables card driver support for the Intel Many Integrated
Core (MIC) device family. The card driver communicates shutdown/
crash events to the host and allows registration/configuration of
virtio devices. Intel MIC X100 devices are currently supported.
If you are building a card kernel for an Intel MIC device then
say M (recommended) or Y, else say N. If unsure say N.
