Merge tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "This is slightly smaller than usual, with the most interesting work being still around RTNL scope reduction. Core: - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter: - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols: - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm. Driver API: - Introduce a unified and structured interface for reporting PHY statistics, exposing consistent data across different H/W via ethtool. - Make timestamping selectable, allow the user to select the desired hwtstamp provider (PHY or MAC) administratively. - Add support for configuring a header-data-split threshold (HDS) value via ethtool, to deal with partial or buggy H/W implementation. - Consolidate DSA drivers Energy Efficiency Ethernet support. - Add EEE management to phylink, making use of the phylib implementation. - Add phylib support for in-band capabilities negotiation. - Simplify how phylib-enabled mac drivers expose the supported interfaces. Tests and tooling: - Make the YNL tool package-friendly to make it easier to deploy it separately from the kernel. - Increase TCP selftest coverage importing several packetdrill test-cases. - Regenerate the ethtool uapi header from the YNL spec, to ease maintenance and future development. - Add YNL support for decoding the link types used in net self-tests, allowing a single build to run both net and drivers/net. Drivers: - Ethernet high-speed NICs: - nVidia/Mellanox (mlx5): - add cross E-Switch QoS support - add SW Steering support for ConnectX-8 - implement support for HW-Managed Flow Steering, improving the rule deletion/insertion rate - support for multi-host LAG - Intel (ixgbe, ice, igb): - ice: add support for devlink health events - ixgbe: add initial support for E610 chipset variant - igb: add support for AF_XDP zero-copy - Meta: - add support for basic RSS config - allow changing the number of channels - add hardware monitoring support - Broadcom (bnxt): - implement TCP data split and HDS threshold ethtool support, enabling Device Memory TCP. - Marvell Octeon: - implement egress ipsec offload support for the cn10k family - Hisilicon (HIBMC): - implement unicast MAC filtering - Ethernet NICs embedded and virtual: - Convert UDP tunnel drivers to NETDEV_PCPU_STAT_DSTATS, avoiding contented atomic operations for drop counters - Freescale: - quicc: phylink conversion - enetc: support Tx and Rx checksum offload and improve TSO performances - MediaTek: - airoha: introduce support for ETS and HTB Qdisc offload - Microchip: - lan78XX USB: preparation work for phylink conversion - Synopsys (stmmac): - support DWMAC IP on NXP Automotive SoCs S32G2xx/S32G3xx/S32R45 - refactor EEE support to leverage the new driver API - optimize DMA and cache access to increase raw RX performances by 40% - TI: - icssg-prueth: add multicast filtering support for VLAN interface - netkit: - add ability to configure head/tailroom - VXLAN: - accepts packets with user-defined reserved bit - Ethernet switches: - Microchip: - lan969x: add RGMII support - lan969x: improve TX and RX performance using the FDMA engine - nVidia/Mellanox: - move Tx header handling to PCI driver, to ease XDP support - Ethernet PHYs: - Texas Instruments DP83822: - add support for GPIO2 clock output - Realtek: - 8169: add support for RTL8125D rev.b - rtl822x: add hwmon support for the temperature sensor - Microchip: - add support for RDS PTP hardware - consolidate periodic output signal generation - CAN: - several DT-bindings to DT schema conversions - tcan4x5x: - add HW standby support - support nWKRQ voltage selection - kvaser: - allowing Bus Error Reporting runtime configuration - WiFi: - the on-going Multi-Link Operation (MLO) effort continues, affecting both the stack and in drivers - mac80211/cfg80211: - Emergency Preparedness Communication Services (EPCS) station mode support - support for adding and removing station links for MLO - add support for WiFi 7/EHT mesh over 320 MHz channels - report Tx power info for each link - RealTek (rtw88): - enable USB Rx aggregation and USB 3 to improve performance - LED support - RealTek (rtw89): - refactor power save to support Multi-Link Operations - add support for RTL8922AE-VS variant - MediaTek (mt76): - single wiphy multiband support (preparation for MLO) - p2p device support - add TP-Link TXE50UH USB adapter support - Qualcomm (ath10k): - support for the QCA6698AQ IP core - Qualcomm (ath12k): - enable MLO for QCN9274 - Bluetooth: - Allow sysfs to trigger hdev reset, to allow recovering devices not responsive from user-space - MediaTek: add support for MT7922, MT7925, MT7921e devices - Realtek: add support for RTL8851BE devices - Qualcomm: add support for WCN785x devices - ISO: allow BIG re-sync" * tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1386 commits) net/rose: prevent integer overflows in rose_setsockopt() net: phylink: fix regression when binding a PHY net: ethernet: ti: am65-cpsw: streamline TX queue creation and cleanup net: ethernet: ti: am65-cpsw: streamline RX queue creation and cleanup net: ethernet: ti: am65-cpsw: ensure proper channel cleanup in error path ipv6: Convert inet6_rtm_deladdr() to per-netns RTNL. ipv6: Convert inet6_rtm_newaddr() to per-netns RTNL. ipv6: Move lifetime validation to inet6_rtm_newaddr(). ipv6: Set cfg.ifa_flags before device lookup in inet6_rtm_newaddr(). ipv6: Pass dev to inet6_addr_add(). ipv6: Convert inet6_ioctl() to per-netns RTNL. ipv6: Hold rtnl_net_lock() in addrconf_init() and addrconf_cleanup(). ipv6: Hold rtnl_net_lock() in addrconf_dad_work(). ipv6: Hold rtnl_net_lock() in addrconf_verify_work(). ipv6: Convert net.ipv6.conf.${DEV}.XXX sysctl to per-netns RTNL. ipv6: Add __in6_dev_get_rtnl_net(). net: stmmac: Drop redundant skb_mark_for_recycle() for SKB frags net: mii: Fix the Speed display when the network cable is not connected sysctl net: Remove macro checks for CONFIG_SYSCTL eth: bnxt: update header sizing defaults ...
