Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
 "Usual collection of small improvements and fixes:

   - Bug fixes and minor improvments in efa, irdma, mlx4, mlx5, rxe,
     hf1, qib, ocrdma

   - bnxt_re support for MSN, which is a new retransmit logic

   - Initial mana support for RC qps

   - Use after free bug and cleanups in iwcm

   - Reduce resource usage in mlx5 when RDMA verbs features are not used

   - New verb to drain shared recieve queues, similar to normal recieve
     queues. This is necessary to allow ULPs a clean shutdown. Used in
     the iscsi rdma target

   - mlx5 support for more than 16 bits of doorbell indexes

   - Doorbell moderation support for bnxt_re

   - IB multi-plane support for mlx5

   - New EFA adaptor PCI IDs

   - RDMA_NAME_ASSIGN_TYPE_USER to hint to userspace that it shouldn't
     rename the device

   - A collection of hns bugs

   - Fix long standing bug in bnxt_re with incorrect endian handling of
     immediate data"
