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" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (38 commits) net/mlx5: increase async EQ to avoid EQ overrun mlx5: fix mlx5_get_vector_affinity to start from completion vector 0 RDMA/hns: Fix the endian problem for hns IB/uverbs: Use the standard kConfig format for experimental IB: Update references to libibverbs IB/hfi1: Add 16B rcvhdr trace support IB/hfi1: Convert kzalloc_node and kcalloc to use kcalloc_node IB/core: Avoid a potential OOPs for an unused optional parameter IB/core: Map iWarp AH type to undefined in rdma_ah_find_type IB/ipoib: Fix for potential no-carrier state IB/hfi1: Show fault stats in both TX and RX directions IB/hfi1: Remove blind constants from 16B update IB/hfi1: Convert PortXmitWait/PortVLXmitWait counters to flit times IB/hfi1: Do not override given pcie_pset value IB/hfi1: Optimize process_receive_ib() IB/hfi1: Remove unnecessary fecn and becn fields IB/hfi1: Look up ibport using a pointer in receive path IB/hfi1: Optimize packet type comparison using 9B and bypass code paths IB/hfi1: Compute BTH only for RDMA_WRITE_LAST/SEND_LAST packet IB/hfi1: Remove dependence on qp->s_hdrwords ...

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
|

rdma-core <https://github.com/linux-rdma/rdma-core>.

IOCTL based ABI support for Infiniband. This allows userspace

These commands are parsed via per-device parsing tree and

enables per-device features.

On demand paging support for the InfiniBand subsystem.

Together with driver support this allows registration of

|
memory regions without pinning their pages, fetching the

pages on demand instead.

This allows the user to config the default GID type that the CM
