Pull rdma fixes from Jason Gunthorpe:
 "A lot of fixes accumulated over the holiday break:

   - Static tool fixes, value is already proven to be NULL, possible
     integer overflow

   - Many bnxt_re fixes:
      - Crashes due to a mismatch in the maximum SGE list size
      - Don't waste memory for user QPs by creating kernel-only
        structures
      - Fix compatability issues with older HW in some of the new HW
        features recently introduced: RTS->RTS feature, work around 9096
      - Do not allow destroy_qp to fail
      - Validate QP MTU against device limits
      - Add missing validation on madatory QP attributes for RTR->RTS
      - Report port_num in query_qp as required by the spec
      - Fix creation of QPs of the maximum queue size, and in the
        variable mode
      - Allow all QPs to be used on newer HW by limiting a work around
        only to HW it affects
      - Use the correct MSN table size for variable mode QPs
      - Add missing locking in create_qp() accessing the qp_tbl
      - Form WQE buffers correctly when some of the buffers are 0 hop
      - Don't crash on QP destroy if the userspace doesn't setup the
        dip_ctx
      - Add the missing QP flush handler call on the DWQE path to avoid
        hanging on error recovery
      - Consistently use ENXIO for return codes if the devices is
        fatally errored

   - Try again to fix VLAN support on iwarp, previous fix was reverted
     due to breaking other cards

   - Correct error path return code for rdma netlink events

   - Remove the seperate net_device pointer in siw and rxe which
     syzkaller found a way to UAF

   - Fix a UAF of a stack ib_sge in rtrs

   - Fix a regression where old mlx5 devices and FW were wrongly
     activing new device features and failing"
