Hi Linus,

Not a big cylce this time, lots of scattered changes.

Thanks,
Jason

  IB/hfi1: Reduce printing of errors during driver shut down (2023-08-22 17:31:45 +0300)

----------------------------------------------------------------
v6.6 merge window RDMA pull request

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
