[openib-general] IB initialization

[Chris Worley]

Hal,

Note that I got an /etc/init.d/openibd script that's getting
everything running (I still don't have IPoIB or MVAPICH2... but I can
live without both).

Now, I'm running Opensm with -V, and it looks as I expected.

This cluster is simple: 9 nodes in one switch.

Thanks,

Chris
