Pull rdma updates from Jason Gunthorpe:
"A smaller cycle this time. Notably we see another new driver, 'Soft
iWarp', and the deletion of an ancient unused driver for nes.

- Revise and simplify the signature offload RDMA MR APIs

- More progress on hoisting object allocation boiler plate code out
of the drivers

- Driver bug fixes and revisions for hns, hfi1, efa, cxgb4, qib,
i40iw

- Tree wide cleanups: struct_size, put_user_page, xarray, rst doc
conversion

- Removal of obsolete ib_ucm chardev and nes driver

- netlink based discovery of chardevs and autoloading of the modules
providing them

- Move more of the rdamvt/hfi1 uapi to include/uapi/rdma

- New driver 'siw' for software based iWarp running on top of netdev,
much like rxe's software RoCE.

- mlx5 feature to report events in their raw devx format to userspace

- Expose per-object counters through rdma tool

- Adaptive interrupt moderation for RDMA (DIM), sharing the DIM core
from netdev"

Merge branch 'siw' into rdma.git for-next

Bernard Metzler says:

====================
This patch set contributes the SoftiWarp driver rebased for latest
rdma-next. SoftiWarp (siw) implements the iWarp RDMA protocol over kernel
TCP sockets. The driver integrates with the linux-rdma framework.

A matching userlevel driver is available as PR at
https://github.com/linux-rdma/rdma-core/pull/536

Many thanks for reviewing and testing the driver, especially to Leon,
Jason, Steve, Doug, Olga, Dennis, Gal. You all helped to significantly
improve the driver over the last year.

Please find below a list of changes and comments, compared to older
versions of the siw driver.

Many thanks!
Bernard.

CHANGES:
========

v3 (this version)
-----------------

- Rebased to rdma-next

- Removed unneccessary initialization of enums in siw-abi.h

- Added comment on sizing of all work queues to power of two.

v2
-----------------

- Changed recieve path CRC calculation to compute CRC32c not
on target buffer after placement, but on original skbuf.
This change severely hurts performance, if CRC is switched
on, since skb must now be walked twice. It is planned to
work on an extension to skb_copy_bits() to fold in CRC
computation.

- Moved debugging to using ibdev_dbg().

- Dropped detailed packet debug printing.

- Removed siw_debug.[ch] files.

- Removed resource tracking, code now relies on restrack of
RDMA midlayer. Only object counting to enforce reported
device limits is left in place.

- Removed all nested switch-case statements.

- Cleaned up header file #include's

- Moved CQ create/destroy to new semantics,
where midlayer creates/destroys containing object.

- Set siw's ABI version to 1 (was 0 before)

- Removed all enum initialization where not needed.

- Fixed MAINTANERS entry for siw driver

- This version stays with the current siw specific
management of user memory (siw_umem_get() vs.
ib_umem_get(), etc.). This, since the current ib_umem
implementation is less efficient for user page lookup
on the fast path, where effciency is important for a
SW RDMA driver.
It is planned to contribute enhancements to the ib_umem
framework, wich makes it suitable for SW drivers as well.

v1 (first version after v9 of siw RFC)
--------------------------------------

- Rebased to 5.2-rc1

- All IDR code got removed.

- Both MR and QP deallocation verbs now synchronously
free the resources referenced by the RDMA mid-layer.

- IPv6 support was added.

- For compatibility with Chelsio iWarp hardware, the RX
path was slightly reworked. It now allows packet intersection
between tagged and untagged RDMAP operations. While not
a defined behavior as of IETF RFC 5040/5041, some RDMA hardware
may intersect an ongoing outbound (large) tagged message, such
as an multisegment RDMA Read Response with sending an untagged
message, such as an RDMA Send frame. This behavior was only
detected in an NVMeF setup, where siw was used at target side,
and RDMA hardware at client side (during file write). siw now
implements two input paths for tagged and untagged messages each,
and allows the intersected placement of both messages.

- The siw kernel abi file got renamed from siw_user.h to siw-abi.h.
