The BSD sources are always the best starting point.   From there,
all I can say is use the opengroup  description and write it yourself.

The glibc implementation is OK as a reference but do NOT take
code from it.  I know you wouldn't do that anyway.

If you get them implemented, submit them with a test in netdemos
and I will merge them. The netdemos examples on real hardware usually
have two interfaces so would be more interesting to test against than
just loopback.

Is that related to MDP from the Navy?  

Please add this to the Wiki list for Free Software that supports
RTEMS when you get far enough. :)
