[openib-general] Performance Degradation with OFED v. Voltaire(lustre)

[Bernadat, Philippe]

Hi Or,

I didn't have time to re-run then non FMR cases.
For FMR VIB and OFED are comparable.
But I will e-run tests for all cases

Right now I am fighting with ib_query_device() that crashes the kernel !
Trying to use this to test the HCA type.
