To enable loopback I'm pretty sure you need an IB link on the card, and a running SM to set the link the ACTIVE. Also, be aware that in my experience loopback is a special case on IB cards and the performance is not good, so testing in this manner may not be valid. If you have a dual port card you'd be better off connecting the ports together and doing your test from port 1 to port 2.
