This patch adds debugfs support to override the Master and Slave data
modes. The settings only take effect prior to a new stream being
prepared/enabled, or on resume.
The test mode can be set to verify data integrity and detect bus
clashes, but can only be used to test capture paths. In this case the
input generated by a Slave source port is replaced by a fixed or
cyclical patterns.

Test modes are required for all SoundWire IP, and help debug
integration issues. In theory each port can be configured with a
different mode but to simplify this patch only offers separate
configurations for the Master and Slave ports - this covers 99% of the
intended cases during platform integration.
The test mode value is set via platform-specific ways.

When WIZ wraps a Cadence Torrent PHY (instead of Cadence Sierra PHY)
there is a difference in the refclk-dig node: Torrent only has two
clocks instead of Sierra's four clocks. Add minItems: 2 to solve this.
Additionally, in our use case we only need to use assigned-clock for a
single clock, but the current binding requires either no assigned-clocks
or two. Fix this by adding minItems: 1 to all the assigned-clock
properties.
There was also an extra trailing whitespace, which this patch removes.

Multi packet TX descriptor support for SKBs.
This series introduces some refactoring of the regular TX data path in
mlx5 and adds the Enhanced TX MPWQE feature support. MPWQE stands for
multi-packet work queue element, and it can serve multiple packets,
reducing the PCI bandwidth spent on control traffic. It should improve
performance in scenarios where PCI is the bottleneck, and xmit_more is
signaled by the kernel. The refactoring done in this series also
improves the packet rate on its own.
MPWQE is already implemented in the XDP tx path, this series adds the
support of MPWQE for regular kernel SKB tx path.
MPWQE is supported from ConnectX-5 and onward, for legacy devices we need
to keep backward compatibility for regular (Single packet) WQE descriptor.
MPWQE is not compatible with certain offloads and features, such as TLS
offload, TSO, nonlinear SKBs. If such incompatible features are in use,
the driver gracefully falls back to non-MPWQE per SKB.
Prior to the final patch "net/mlx5e: Enhanced TX MPWQE for SKBs" that adds
the actual support, Maxim did some refactoring to the tx data path to
split it into stages and smaller helper functions that can be utilized and
reused for both legacy and new MPWQE feature.
Performance testing:
UDP performance is improved in a single stream pktgen test:
Packet rate: 16.86 Mpps (±0.15 Mpps) -> 20.94 Mpps (±0.33 Mpps)
Instructions per packet: 434 -> 329
Cycles per packet: 158 -> 123
Instructions per cycle: 2.75 -> 2.67
TCP and XDP_TX single stream tests show no performance difference.
MPWQE can reduce PCI bandwidth:
PCI Gen2, pktgen at fixed rate of 36864000 pps on 24 CPU cores:
Inbound PCI utilization with MPWQE off: 80.3%
Inbound PCI utilization with MPWQE on: 59.0%
PCI Gen3, pktgen at fixed rate of 56064000 pps on 24 CPU cores:
Inbound PCI utilization with MPWQE off: 65.4%
Inbound PCI utilization with MPWQE on: 49.3%
MPWQE can also reduce CPU load, increasing the packet rate in case of
CPU bottleneck:
PCI Gen2, pktgen at full rate on 24 CPU cores:
Packet rate with MPWQE off: 37.5 Mpps
Packet rate with MPWQE on: 49.0 Mpps
PCI Gen3, pktgen at full rate on 24 CPU cores:
Packet rate with MPWQE off: 57.0 Mpps
Packet rate with MPWQE on: 66.8 Mpps
Burst size in all pktgen tests is 32.

sg_init_table() zeroes its first argument, so the allocation of that
argument doesn't have to.
The semantic patch that makes this change is as follows:

Occasionally ib_write_bw crash is seen due to access of a pd object in
i40iw_sc_qp_destroy after it is freed. Destroy qp is not synchronous in
i40iw and thus the iwqp object could be referencing a pd object that is
freed by ib core as a result of successful return from i40iw_destroy_qp.
Wait in i40iw_destroy_qp till all QP references are released and destroy
the QP and its associated resources before returning. Switch to use the
refcount API vs atomic API for lifetime management of the qp.

The keep alive received counter is a software stat, keep it grouped with
all other software stats. Since all stored stats are software stats,
remove the efa_sw_stats struct and use efa_stats instead.

Use rdma_restrack_set_name() and rdma_restrack_parent_name() instead of
tricky uses of rdma_restrack_attach_task()/rdma_restrack_uadd().
This uniformly makes all restracks add'd using rdma_restrack_add().

Have a single rdma_restrack_add() that adds an entry, there is no reason
to split the user/kernel here, the rdma_restrack_set_task() is responsible
for this difference.
This patch prepares the code to the future requirement of making restrack
is mandatory for managing ib objects.
