Pull more rdma updates from Doug Ledford:
"Items of note:
- two patches fix a regression in the 4.15 kernel. The 4.14 kernel
worked fine with NVMe over Fabrics and mlx5 adapters. That broke in
4.15. The fix is here.
- one of the patches (the endian notation patch from Lijun) looks
like a lot of lines of change, but it's mostly mechanical in
nature. It amounts to the biggest chunk of change in it (it's about
2/3rds of the overall pull request).
Summary:
- Clean up some function signatures in rxe for clarity
- Tidy the RDMA netlink header to remove unimplemented constants
- bnxt_re driver fixes, one is a regression this window.
- Minor hns driver fixes
- Various fixes from Dan Carpenter and his tool
- Fix IRQ cleanup race in HFI1
- HF1 performance optimizations and a fix to report counters in the right units
- Fix for an IPoIB startup sequence race with the external manager
- Oops fix for the new kabi path
- Endian cleanups for hns
- Fix for mlx5 related to the new automatic affinity support"

Userspace InfiniBand Management Datagram (MAD) support. This
|

is the kernel side of the userspace MAD support, which allows

userspace processes to send and receive MADs. You will also

Userspace InfiniBand access support. This enables the

kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand
|
|
hardware for fast-path operations. You will also need
|

libibverbs, libibcm and a hardware driver library from
