Here is a suggested patch for adding the QLogic QLE7240 and QLE7280
DDR HCA cards to the openib params file.

I would like the MTU to default to 4K for these HCAs but I don't see
any code using the ibv_port_attr.active_mtu field to limit the MTU
to the active MTU. If you like, I can try to make a patch to do this.
