     mlx5, irdma, qedr

   - rtrs ULP bug fixes an improvments

   - Additional counters for bnxt_re

   - Support verbs CQ notifications in EFA

   - Continued reworking and fixing of rxe

   - netlink control to enable/disable optional device counters

   - rxe now can use AH objects for its UD path, fixing various bugs in
     the process

   - Add DMABUF support to EFA"
