ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

Merge tag 'net-next-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Replace busylock at the Tx queuing layer with a lockless list.

Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.

- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.

Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.

Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.

- Optimize the NAPI skb cache, make it larger, use it in more paths.

- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).

- Various data structure layout and prefetch optimizations from Eric.

- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.

- Extend threaded NAPI polling to allow the kthread busy poll for
packets.

- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.

- Support memcg accounting of MPTCP socket memory.

- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.

- Improve heuristics for when to kick off AF_UNIX garbage collection.

- Allow users to control TCP SACK compression, and default to 33% of
RTT.

- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.

- Preserve skb metadata space across skb_push / skb_pull operations.

- Support for IPIP encapsulation in the nftables flowtable offload.

- Support appending IP interface information to ICMP messages (RFC
5837).

- Support setting max record size in TLS (RFC 8449).

- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.

- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.

- Let users configure the number of write buffers in SMC.

- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.

- Some conversions away from the crypto_ahash API, from Eric Biggers.

- Some preparations for slimming down struct page.

- YAML Netlink protocol spec for WireGuard.

- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.

Driver API:

- Add CAN XL support to the CAN Netlink interface.

- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as
defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.

- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).

- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.

- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.

- Add standard device stats for PSP crypto offload.

- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.

- Add uAPI defines for 1.6Tbps link modes.

Device drivers:

- Add Motorcomm YT921x gigabit Ethernet switch support.

- Add MUCSE driver for N500/N210 1GbE NIC series.

- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.

- Add (and convert most drivers to) a dedicated ethtool callback for
reading the Rx ring count.

- Significant refactoring efforts in the STMMAC driver, which
supports Synopsys turn-key MAC IP integrated into a ton of SoCs.

Merge branch 'tools-ynl-turn-the-page-pool-sample-into-a-real-tool'

Jakub Kicinski says:

====================
tools: ynl: turn the page-pool sample into a real tool

The page-pool YNL sample is quite useful. It's helps calculate
recycling rate and memory consumption. Since we still haven't
figured out a way to integrate with iproute2 (not for the lack
of thinking how to solve it) - create a ynltool command in ynl.

Add page-pool and qstats support.

Most commands can use the Python YNL CLI directly but low level
stats often need aggregation or some math on top to be useful.
Specifically in this patch set:
- page pool stats are aggregated and recycling rate computed
- per-queue stats are used to compute traffic balance across queues

tools: ynltool: create skeleton for the C command

Based on past discussions it seems like integration of YNL into
iproute2 is unlikely. YNL itself is not great as a C library,
since it has no backward compat (we routinely change types).

Most of the operations can be performed with the generic Python
CLI directly. There is, however, a handful of operations where
summarization of kernel output is very useful (mostly related
to stats: page-pool, qstat).

Create a command (inspired by bpftool, I think it stood the test
of time reasonably well) to be able to plug the subcommands into.
