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

Pull rdma updates from Jason Gunthorpe:
 "Many small changes across the subystem, some highlights:

   - Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma,
     mthca, hns, and bnxt_re

   - siw now works over tunnel and other netdevs with a MAC address by
     removing assumptions about a MAC/GID from the connection manager

   - "Doorbell Pacing" for bnxt_re - this is a best effort scheme to
     allow userspace to slow down the doorbell rings if the HW gets full

   - irdma egress VLAN priority, better QP/WQ sizing

   - rxe bug fixes in queue draining and srq resizing

   - Support more ethernet speed options in the core layer

   - DMABUF support for bnxt_re

   - Multi-stage MTT support for erdma to allow much bigger MR
     registrations

   - A irdma fix with a CVE that came in too late to go to -rc, missing
     bounds checking for 0 length MRs"
