 "This cycle mainly saw lots of bug fixes and clean up code across the
  core code and several drivers, few new functional changes were made.

   - Many cleanup and bug fixes for hns

   - Various small bug fixes and cleanups in hfi1, mlx5, usnic, qed,
     bnxt_re, efa

   - Share the query_port code between all the iWarp drivers

   - General rework and cleanup of the ODP MR umem code to fit better
     with the mmu notifier get/put scheme

   - Support rdma netlink in non init_net name spaces

   - mlx5 support for XRC devx and DC ODP"
