The Darwin/Mac OS X scheme only deals with IOKit because that's where
the drivers live. The protocol implementation is in the directory
'xnu/osfmk/kdp'. It's in essence a UDP protocol, and is implemented
without using any of the system's networking scheme (except for mbufs).
The implementation is polling. The implementation is pretty
light-weight.
