c7ff819aef RDMA/core: Introduce shared CQ pool API
Allow a ULP to ask the core to provide a completion queue based on a
least-used search on a per-device CQ pools. The device CQ pools grow in a
lazy fashion when more CQs are requested.

This feature reduces the amount of interrupts when using many QPs.  Using
shared CQs allows for more effcient completion handling. It also reduces
the amount of overhead needed for CQ contexts.

Test setup:
Intel(R) Xeon(R) Platinum 8176M CPU @ 2.10GHz servers.
Running NVMeoF 4KB read IOs over ConnectX-5EX across Spectrum switch.
TX-depth = 32. The patch was applied in the nvme driver on both the target
and initiator. Four controllers are accessed from each core. In the
current test case we have exposed sixteen NVMe namespaces using four
different subsystems (four namespaces per subsystem) from one NVM port.
Each controller allocated X queues (RDMA QPs) and attached to Y CQs.
Before this series we had X == Y, i.e for four controllers we've created
total of 4X QPs and 4X CQs. In the shared case, we've created 4X QPs and
only X CQs which means that we have four controllers that share a
completion queue per core. Until fourteen cores there is no significant
change in performance and the number of interrupts per second is less than
a million in the current case.

spi: Convert DW SPI binding to DT schema
Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces two DW SPI legacy
bare text bindings with YAML file. As before the bindings file states
that the corresponding dts node is supposed to be compatible either
with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel
vendors-specific controllers, to have registers, interrupts and clocks
properties. Though in case of Microsemi version of the controller
there must be two registers resources specified. Properties like
clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device
sub-nodes are optional.

3446cbd2d5 RDMA/core: Add protection for shared CQs used by ULPs
A pre-step for adding shared CQs. Add the infrastructure to prevent shared
CQ users from altering the CQ configurations. For now all cqs are marked
as private (non-shared). The core driver should use the new force
functions to perform resize/destroy/moderation changes that are not
allowed for users of shared CQs.

802dcc7fc5 RDMA/mlx5: Support TX port affinity for VF drivers in LAG mode
The mlx5 VF driver doesn't set QP tx port affinity because it doesn't know
if the lag is active or not, since the "lag_active" works only for PF
interfaces. In this case for VF interfaces only one lag is used which
brings performance issue.

Add a lag_tx_port_affinity CAP bit; When it is enabled and
"num_lag_ports > 1", then driver always set QP tx affinity, regardless
of lag state.

d4ee7f3a44 RDMA/srpt: Make debug output more detailed
Since the session name by itself is not sufficient to uniquely identify a
queue pair, include the queue pair number. Show the ASCII channel state
name instead of the numeric value. This change makes the ib_srpt debug
output more consistent.

87fee61c35 RDMA/srp: Make the channel count configurable per target
Increase the flexibility of the SRP initiator driver by making the channel
count configurable per target instead of only providing a kernel module
parameter for configuring the channel count.

3221546948 null_blk: force complete for timeout request
The commit 7b11eab041 ("blk-mq: blk-mq: provide forced completion
method") exports new API to force a request to complete without error
injection.

There should be no error injection when completing a request by timeout
handler.

Otherwise, the below would hang because timeout handler is failed.

echo 100 > /sys/kernel/debug/fail_io_timeout/probability
echo 1000 > /sys/kernel/debug/fail_io_timeout/times
echo 1 > /sys/block/nullb0/io-timeout-fail
dd if=/dev/zero of=/dev/nullb0 bs=512 count=1 oflag=direct

With this patch, the timeout handler is able to complete the IO.

982d7287f8 mwifiex: Add support for NL80211_ATTR_MAX_AP_ASSOC_STA
SD8997 firmware sends TLV_TYPE_MAX_CONN with struct hw_spec_max_conn to
inform kernel about maximum number of p2p connections and stations in AP
mode.

During initialization of SD8997 wifi chip kernel prints warning:

  mwifiex_sdio mmc0:0001:1: Unknown GET_HW_SPEC TLV type: 0x217

This patch adds support for parsing TLV_TYPE_MAX_CONN (0x217) and sets
appropriate cfg80211 member 'max_ap_assoc_sta' from retrieved structure.

It allows userspace to retrieve NL80211_ATTR_MAX_AP_ASSOC_STA attribute.

11e7a91994 airo: Fix read overflows sending packets
The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from
skb->data even when skb->len is less than ETH_ZLEN so it leads to a read
overflow.

The fix is to pad skb->data to at least ETH_ZLEN bytes.
