Perhaps, but it is probably the cleanest solution, allowing iWarp and
IB specific stuff to be totally independent with no header
interdependencies between the two transports.  It also follows the
existing precendent of how struct device is the first member of struct
ib_device.

While it is a larger change, I don't think it's particularily more
complicated or more difficult - it's just bigger.
