[ofa-general] MPI IB Errors

[John Leidel]

Err.... I don't seem to have any of the typical IB diagnostics tools.  All
they [ie, i didn't originally install this machine] had running in the first
place were the IB modules resident with the 2.6.9-42 redhat kernel.

I'm debating on whether I should go install the CISCO IB Roll to make sure I
have all the necessary tools in place.
