[openib-general] 2.6.17-rc1 IPoIB netperf results

[Matt Leininger]

Here are the latest IPoIB results:

For mthca I saw a range of 380-424 MB/s.  The local CPU utilization on
the send side dropped for the 380 MB/s, from 98% to 70%

For ipath it was 310 MB/s.  The local CPU utilization on the send side
was always around 30%.
