I found that actually we don't have to touch this one which
only used by HW driver currently.

I think we can leave these scenes there in device driver, since
vendor could have different way to classify the usage of transfer
and link layer.

Our purpose is to introduce IB core management approach, which
may not be applicable on device level, maybe we can just pass them :-)
