3  * Common (shared) DLPI test routines.
4  * Mostly pretty boring boilerplate sorta stuff.
5  * These can be split into individual library routines later
6  * but it's just convenient to keep them in a single file
7  * while they're being developed.

9  * Not supported:
10  *   Connection Oriented stuff
11  *   QOS stuff
