Subject: [PATCH] Do a better job of validating IP and MAC addresses in
 network.rng

IP addresses and MAC addresses had been defined in the RNG simply as
<text/> meaning that, according to the RNG, any string could go in
there. Of course the C parsing code does a much better job of
validating, but we may as well have this describing the contents
accurately (even though it's currently only used during "make check").
