Linus Torvalds f34b2cf178 RDMA merge window pull request
This is significantly bug fixes and general cleanups. The noteworthy new
 features are fairly small:
 
 - XRC support for HNS and improves RQ operations
 
 - Bug fixes and updates for hns, mlx5, bnxt_re, hfi1, i40iw, rxe, siw and
   qib
 
 - Quite a few general cleanups on spelling, error handling, static checker
   detections, etc
 
 - Increase the number of device ports supported beyond 255. High port
   count software switches now exist
 
 - Several bug fixes for rtrs
 
 - mlx5 Device Memory support for host controlled atomics
 
 - Report SRQ tables through to rdma-tool

Yevgeny Kliteynik aeacb52a8d net/mlx5: DR, Add support for isolate_vl_tc QP
When using SW steering, rule insertion rate depends on the RDMA RC QP
performance used for writing to the ICM. During stress this QP is competing
on the HW resources with all the other QPs that are used to send data.
To protect SW steering QP's performance in such cases, we set this QP to
use isolated VL. The VL number is reserved by FW and is not exposed to the
driver.
Support for this QP on isolated VL exists only when both force-loopback and
isolate_vl_tc capabilities are set.

Maxim Mikityanskiy 214baf2287 net/mlx5e: Support HTB offload
This commit adds support for HTB offload in the mlx5e driver.

Performance:

  NIC: Mellanox ConnectX-6 Dx
  CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz (24 cores with HT)

  100 Gbit/s line rate, 500 UDP streams @ ~200 Mbit/s each
  48 traffic classes, flower used for steering
  No shaping (rate limits set to 4 Gbit/s per TC) - checking for max
  throughput.

  Baseline: 98.7 Gbps, 8.25 Mpps
  HTB: 6.7 Gbps, 0.56 Mpps
  HTB offload: 95.6 Gbps, 8.00 Mpps

Limitations:

1. 256 leaf nodes, 3 levels of depth.

2. Granularity for ceil is 1 Mbit/s. Rates are converted to weights, and
the bandwidth is split among the siblings according to these weights.
Other parameters for classes are not supported.

Ethtool statistics support for QoS SQs are also added. The counters are
called qos_txN_*, where N is the QoS queue number (starting from 0, the
numeration is separate from the normal SQs), and * is the counter name
(the counters are the same as for the normal SQs).

Ron Diskin 7d0314b11c net/mlx5e: Modify uplink state on interface up/down
When setting the PF interface up/down, notify the firmware to update
uplink state via MODIFY_VPORT_STATE, when E-Switch is enabled.

This behavior will prevent sending traffic out on uplink port when PF is
down, such as sending traffic from a VF interface which is still up.
Currently when calling mlx5e_open/close(), the driver only sends PAOS
command to notify the firmware to set the physical port state to
up/down, however, it is not sufficient. When VF is in "auto" state, it
follows the uplink state, which was not updated on mlx5e_open/close()
before this patch.

When switchdev mode is enabled and uplink representor is first enabled,
set the uplink port state value back to its FW default "AUTO".

Eran Ben Elisha 88b3d5c90e net/mlx5e: Fix port buffers cell size value
Device unit for port buffers size, xoff_threshold and xon_threshold is
cells. Fix a bug in driver where cell unit size was hard-coded to
128 bytes. This hard-coded value is buggy, as it is wrong for some hardware
versions.

Driver to read cell size from SBCAM register and translate bytes to cell
units accordingly.

In order to fix the bug, this patch exposes SBCAM (Shared buffer
capabilities mask) layout and defines.

If SBCAM.cap_cell_size is valid, use it for all bytes to cells
calculations. If not valid, fallback to 128.

Cell size do not change on the fly per device. Instead of issuing SBCAM
access reg command every time such translation is needed, cache it in
mlx5e_dcbx as part of mlx5e_dcbnl_initialize(). Pass dcbx.port_buff_cell_sz
as a param to every function that needs bytes to cells translation.

While fixing the bug, move MLX5E_BUFFER_CELL_SHIFT macro to
en_dcbnl.c, as it is only used by that file.

For a user to be able to request a QP number on QP creation, the MKEY_BY_NAME
