You don't=20 have to replace the kernel on the target system for this test. Regardin= g=20 which InfiniBand stack to use at the initiator side in combination with= =20 kernel 3.6: unless there is something I do not yet know about, it is=20 fine to use the InfiniBand stack included in that kernel and it is not=20 necessary to install OFED for this test.
