This is the kernel space on the remote side...  I chose ibping only as an
example.  As we discussed before finding the LID/GID was a pain in the butt.
This tool makes it easier...

# odev7 /root > ib_sa_query --help
Usage: ib_sa_query [-h -d -P -L -G][<name>]
   Query's node records by default
   -d enable osm debugging
   -P get Pathrecord info
   -L Return just the Lid of the name specified
   -G Return just the Guid of the name specified

ib_sa_query just query's the SA.  The -L option returns the LID found to allow
the use with the other "standard" diags.  The plan was to combine this into the
diags directly but I found it easier to just build a separate tool as I learned
the interfaces.

And of course this depends on something setting up the node descriptions
correctly.  Which I have a script for if anyone is interested.
