Surely, i will modify the location of RoCE driver code after disscussed in next patch

Here, v1 stands for hw, that is, we support v1 of our hw.

    Surely, i have pay attention to the patch, but i consider that it is not better to
split the patch into small patch. because it will the base function of RoCE.
    For your advice, i will make further efforts to taking a discussion how to reslove the question.
