I would not recommend reconfiguring your SM for this situation.
Instead, you most likely have a bad cable or possibly a bad HCA or
switch port. All IB products shipped within the last 6 years support
10g, so the fact your system has negotiated to 2.5g indicates a problem
with the link.
Bad or poorly connected cables are the typical cause.
