Mostly. The only aspect of which I think that it is missing in the API is the alignment requirement for the addresses in ib_indir_reg_list.sg_list. Is byte alignment sufficient ? If so, will all HCA vendors be able to support this or do we perhaps need to add a member in the device attributes structure that declares what the alignment requirements are ?
