Didn't get around to it.  Instead, I was fixing a buffer overflow
problem in openmpi (reuse of the len variable without resetting it to
the correct value after the bottom of the loop does len = strlen(desc);
causes the snprintf() in the loop to trigger as a buffer overflow when
compiled with FORTIFY_SOURCE, patch attached) and reviewing arpingib
(which I'm going to remove from the ipoibtools and fix the native arping
in RHEL5 to work properly over IB without needing a new flag, the -A or
-U flags should be sufficient assuming those modes worked at all over IB
which they don't in either the native arping or the patched arpingib in
ipoibtools).  I should get to it today though.
