This merge includes updates to bonding driver needed for the rdma stack,
to avoid conflicts with the RDMA branch.
Maor Gottlieb Says:
====================
Bonding: Add support to get xmit slave
The following series adds support to get the LAG master xmit slave by
introducing new .ndo - ndo_get_xmit_slave. Every LAG module can
implement it and it first implemented in the bond driver.
This is follow-up to the RFC discussion [1].
The main motivation for doing this is for drivers that offload part
of the LAG functionality. For example, Mellanox Connect-X hardware
implements RoCE LAG which selects the TX affinity when the resources
are created and port is remapped when it goes down.
The first part of this patchset introduces the new .ndo and add the
support to the bonding module.
The second part adds support to get the RoCE LAG xmit slave by building
skb of the RoCE packet based on the AH attributes and call to the new
.ndo.
The third part change the mlx5 driver driver to set the QP's affinity
port according to the slave which found by the .ndo.

mlx5 updates for both net-next and rdma-next:
1) HW bits and definitions for TLS and IPsec offlaods
2) Release all pages capability bits
3) New command interface helpers and some code cleanup as a result
4) Move qp.c out of mlx5 core driver into mlx5_ib rdma driver

Add new TX WQE field for Connect-X6DX trailer insertion support,
when set, the HW adds a trailer to the packet, the WQE trailer
association flags are used to set to HW the header which the
trailer belongs.

The imm_inval_pkey field can hold four different types of data,
depends on the usage, the data could be one of the below:
- Immediate field of the received message
- Invalidate rkey
- Pkey of the packet
- Flow table metadata
Current implementation doesn't reflect the intended usage of the
field at usage time.
Reflect the different types by replace this field with a union,
modify code where this field is used to reflect its intended
usage.

Currently the FPGA IPsec is the only hw implementation of the IPsec
acceleration api, and so the mlx5_accel_esp_create_hw_context was
wrongly made to suit this HW api, among other in its parameter list
and some of its parameter endianness.
This implementation might not be suitable for different HW.
Refactor by group and pass all function arguments of
mlx5_accel_esp_create_hw_context in common mlx5_accel_esp_xfrm_attrs
struct field of mlx5_accel_esp_xfrm struct and correct the endianness
according to the HW being called.

mlx5 core users are encouraged to use low level API (mlx5_cmd_exec)
without the need of helper functions, do this for q counters, remove
helper functions and call mlx5_cmd_exec directly from users.
This will help reduce the total amount of code and reduction of the
mlx5_core symbol table.

Many mlx5_cmd_exec() callers are not interested in the output from that
command or have standard in/out structures. Those callers simply allocate
those structure on the stack and use sizeof() to provide in/out arguments.
In this naive approach provide simplified versions of mlx5_cmd_exec().

Pull rdma updates from Jason Gunthorpe:
"The majority of the patches are cleanups, refactorings and clarity
improvements.
This cycle saw some more activity from Syzkaller, I think we are now
clean on all but one of those bugs, including the long standing and
obnoxious rdma_cm locking design defect. Continue to see many drivers
getting cleanups, with a few new user visible features.
Summary:
- Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1
- Lots of cleanup patches for hns
- Convert more places to use refcount
- Aggressively lock the RDMA CM code that syzkaller says isn't
working
- Work to clarify ib_cm
- Use the new ib_device lifecycle model in bnxt_re
- Fix mlx5's MR cache which seems to be failing more often with the
new ODP code
- mlx5 'dynamic uar' and 'tx steering' user interfaces"
