* GNU Radio plugin "gr-kernel" for device usage will be on:

*
- * TODO:
- * Help is very highly welcome for these + all the others you could imagine:
- * - move controls to V4L2 API
- * - use libv4l2 for stream format conversions
- * - gr-kernel: switch to v4l2_mmap (current read eats a lot of cpu)
- * - SDRSharp support
