IB/ehca: MR/MW structure refactoring
- Rename struct ehca_mr fields to clearly distinguish between kernel and HW page size. - Sort struct ehca_mr_pginfo into a common part and a union containing specific fields for physical, user and fast MR Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
