ASoC: Fixes for v6.18
A moderately large collection of driver specific fixes, plus a few new quirks and device IDs. The NAU8821 changes are a little large but more in mechanical ways than in ways that are complex.

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism has some similarities with IPsec and TLS, but offers superior HW offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than one congestion notification signal per RTT and is a building block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA hosts, this improves TCP and UDP RX performances significantly on such HW
- Increase the default socket memory buffer limits from 256K to 4M to better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making dump operating scaling linearly and avoiding unneeded synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per bridge instead of one entry per port; this makes the dump order of magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently introduced core infrastructure (skb deferral free) and adopting recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing code duplication
- Supports pulling data from an skb frag into the linear area of an XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML parser
Driver API:
- Support using IPv6 Flow Label in Rx hash computation and RSS queue selection
- Introduce API for fetching the DMA device for a given queue, allowing TCP zerocopy RX on more H/W setups
- Make XDP helpers compatible with unreadable memory, allowing more easily building DevMem-enabled drivers with a unified XDP/skbs datapath
- Add a new dedicated ethtool callback enabling drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration
- Introduce a burst period for the health reporter, allowing better handling of multiple errors due to the same root cause
- Support for DPLL phase offset exponential moving average, controlling the average smoothing factor
Device drivers:
- Add a new Huawei driver for 3rd gen NIC (hinic3)
- Add a new SpacemiT driver for K1 ethernet MAC
- Add a generic abstraction for shared memory communication devices (dibps)
- Ethernet high-speed NICs: - nVidia/Mellanox: - Use multiple per-queue doorbell, to avoid MMIO contention issues - support adjacent functions, allowing them to delegate their SR-IOV VFs to sibling PFs - support RSS for IPSec offload - support exposing raw cycle counters in PTP and mlx5 - support for disabling host PFs. - Intel (100G, ice, idpf): - ice: support for SRIOV VFs over an Active-Active link aggregate - ice: support for firmware logging via debugfs - ice: support for Earliest TxTime First (ETF) hardware offload - idpf: support basic XDP functionalities and XSk - Broadcom (bnxt): - support Hyper-V VF ID - dynamic SRIOV resource allocations for RoCE - Meta (fbnic): - support queue API, zero-copy Rx and Tx - support basic XDP functionalities - devlink health support for FW crashes and OTP mem corruptions - expand hardware stats coverage to FEC, PHY, and Pause - Wangxun: - support ethtool coalesce options - support for multiple RSS contexts
- Ethernet virtual: - Macsec: - replace custom netlink attribute checks with policy-level checks - Bonding: - support aggregator selection based on port priority - Microsoft vNIC: - use page pool fragments for RX buffers instead of full pages to improve memory efficiency
- Ethernet NICs consumer, and embedded: - Qualcomm: support Ethernet function for IPQ9574 SoC - Airoha: implement wlan offloading via NPU - Freescale - enetc: add NETC timer PTP driver and add PTP support - fec: enable the Jumbo frame support for i.MX8QM - Renesas (R-Car S4): - support HW offloading for layer 2 switching - support for RZ/{T2H, N2H} SoCs - Cadence (macb): support TAPRIO traffic scheduling - TI: - support for Gigabit ICSS ethernet SoC (icssm-prueth) - Synopsys (stmmac): a lot of cleanups
- Ethernet PHYs: - Support 10g-qxgmi phy-mode for AQR412C, Felix DSA and Lynx PCS driver - Support bcm63268 GPHY power control - Support for Micrel lan8842 PHY and PTP - Support for Aquantia AQR412 and AQR115
- CAN: - a large CAN-XL preparation work - reorganize raw_sock and uniqframe struct to minimize memory usage - rcar_canfd: update the CAN-FD handling
- WiFi: - extended Neighbor Awareness Networking (NAN) support - S1G channel representation cleanup - improve S1G support
- WiFi drivers: - Intel (iwlwifi): - major refactor and cleanup - Broadcom (brcm80211): - support for AP isolation - RealTek (rtw88/89) rtw88/89: - preparation work for RTL8922DE support - MediaTek (mt76): - HW restart improvements - MLO support - Qualcomm/Atheros (ath10k): - GTK rekey fixes

Merge branch 'selftest-packetdrill-import-tfo-server-tests'
Kuniyuki Iwashima says:
==================== selftest: packetdrill: Import TFO server tests.
The series imports 15 TFO server tests from google/packetdrill and adds 2 more tests.
The repository has two versions of tests for most scenarios; one uses the non-experimental option (34), and the other uses the experimental option (255) with 0xF989.
Basically, we only import the non-experimental version of tests, and for the experimental option, tcp_fastopen_server_experimental_option.pkt is added.
The following tests are not (yet) imported:
* icmp-baseline.pkt * simple1.pkt / simple2.pkt / simple3.pkt
The former is completely covered by icmp-before-accept.pkt.
The later's delta is the src/dst IP pair to generate a different cookie, but supporting dualstack requires churn in ksft_runner.sh, so defered to future series. Also, sockopt-fastopen-key.pkt covers the same function.
The following tests have the experimental version only, so converted to the non-experimental option:
* client-ack-dropped-then-recovery-ms-timestamps.pkt * sockopt-fastopen-key.pkt
For the imported tests, these common changes are applied.
* Add SPDX header * Adjust path to default.sh * Adjust sysctl w/ set_sysctls.py * Use TFO_COOKIE instead of a raw hex value * Use SOCK_NONBLOCK for socket() not to block accept() * Add assertions for TCP state if commented * Remove unnecessary delay (e.g. +0.1 setsockopt(SO_REUSEADDR), etc)
With this series, except for simple{1,2,3}.pkt, we can remove TFO server tests in google/packetdrill. ====================

selftest: packetdrill: Import opt34/reset-* tests.
This imports the non-experimental version of opt34/reset-*.pkt.
| Child | RST | sk_err | ---------------------------------+---------+-------------------------------+---------+ reset-after-accept.pkt | TFO | after accept(), SYN_RECV | read() | reset-close-with-unread-data.pkt | TFO | after accept(), SYN_RECV | write() | reset-before-accept.pkt | TFO | before accept(), SYN_RECV | read() | reset-non-tfo-socket.pkt | non-TFO | before accept(), ESTABLISHED | write() |
The first 3 files test scenarios where a SYN_RECV socket receives RST before/after accept() and data in SYN must be read() without error, but the following read() or fist write() will return ECONNRESET.
The last test is similar but with non-TFO socket.
