Pull networking updates from Jakub Kicinski: "Core & protocols: - Continue Netlink conversions to per-namespace RTNL lock (IPv4 routing, routing rules, routing next hops, ARP ioctls) - Continue extending the use of netdev instance locks. As a driver opt-in protect queue operations and (in due course) ethtool operations with the instance lock and not RTNL lock. - Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance. - Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring. - Optimize MPTCP performance in single subflow mode by 29%. - Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x. - Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock. Bring an additional 229% improvement by tweaking hash distribution. - Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%. - Avoid skb_clone() dance in ping_rcv() to improve performance under ping flood. - Avoid FIB lookup in netfilter if socket is available, 20% perf win. - Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles. There are up to 4 namespace roles but we used to have just 2 netns pointer arguments, interpreted differently based on context. - Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access. - Add a new sysctl and sockopt for capping max retransmit timeout in TCP. - Support masking port and DSCP in routing rule matches. - Support dumping IPv4 multicast addresses with RTM_GETMULTICAST. - Support specifying at what time packet should be sent on AF_XDP sockets. - Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users. - Add Netlink YAML spec for WiFi (nl80211) and conntrack. - Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module. - Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging. - Allow users to specify source port range for GENEVE tunnels. - netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata Driver API: - Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers. Delegate the responsibilities to phylink where possible. Improve its handling in phylib. - Support symmetric OR-XOR RSS hashing algorithm. - Support tracking and preserving IRQ affinity by NAPI itself. - Support loopback mode speed selection for interface selftests. Device drivers: - Remove the IBM LCS driver for s390 - Remove the sb1000 cable modem driver - Add support for SFP module access over SMBus - Add MCTP transport driver for MCTP-over-USB - Enable XDP metadata support in multiple drivers - Ethernet high-speed NICs: - Broadcom (bnxt): - add PCIe TLP Processing Hints (TPH) support for new AMD platforms - support dumping RoCE queue state for debug - opt into instance locking - Intel (100G, ice, idpf): - ice: rework MSI-X IRQ management and distribution - ice: support for E830 devices - iavf: add support for Rx timestamping - iavf: opt into instance locking - nVidia/Mellanox: - mlx4: use page pool memory allocator for Rx - mlx5: support for one PTP device per hardware clock - mlx5: support for 200Gbps per-lane link modes - mlx5: move IPSec policy check after decryption - AMD/Solarflare: - support FW flashing via devlink - Cisco (enic): - use page pool memory allocator for Rx - enable 32, 64 byte CQEs - get max rx/tx ring size from the device - Meta (fbnic): - support flow steering and RSS configuration - report queue stats - support TCP segmentation - support IRQ coalescing - support ring size configuration - Marvell/Cavium: - support AF_XDP - Wangxun: - support for PTP clock and timestamping - Huawei (hibmcge): - checksum offload - add more statistics - Ethernet virtual: - VirtIO net: - aggressively suppress Tx completions, improve perf by 96% with 1 CPU and 55% with 2 CPUs - expose NAPI to IRQ mapping and persist NAPI settings - Google (gve): - support XDP in DQO RDA Queue Format - opt into instance locking - Microsoft vNIC: - support BIG TCP - Ethernet NICs consumer, and embedded: - Synopsys (stmmac): - cleanup Tx and Tx clock setting and other link-focused cleanups - enable SGMII and 2500BASEX mode switching for Intel platforms - support Sophgo SG2044 - Broadcom switches (b53): - support for BCM53101 - TI: - iep: add perout configuration support - icssg: support XDP - Cadence (macb): - implement BQL - Xilinx (axinet): - support dynamic IRQ moderation and changing coalescing at runtime - implement BQL - report standard stats - MediaTek: - support phylink managed EEE - Intel: - igc: don't restart the interface on every XDP program change - RealTek (r8169): - support reading registers of internal PHYs directly - increase max jumbo packet size on RTL8125/RTL8126 - Airoha: - support for RISC-V NPU packet processing unit - enable scatter-gather and support MTU up to 9kB - Tehuti (tn40xx): - support cards with TN4010 MAC and an Aquantia AQR105 PHY - Ethernet PHYs: - support for TJA1102S, TJA1121 - dp83tg720: add randomized polling intervals for link detection - dp83822: support changing the transmit amplitude voltage - support for LEDs on 88q2xxx - CAN: - canxl: support Remote Request Substitution bit access - flexcan: add S32G2/S32G3 SoC - WiFi: - remove cooked monitor support - strict mode for better AP testing - basic EPCS support - OMI RX bandwidth reduction support - batman-adv: add support for jumbo frames - WiFi drivers: - RealTek (rtw88): - support RTL8814AE and RTL8814AU - RealTek (rtw89): - switch using wiphy_lock and wiphy_work - add BB context to manipulate two PHY as preparation of MLO - improve BT-coexistence mechanism to play A2DP smoothly - Intel (iwlwifi): - add new iwlmld sub-driver for latest HW/FW combinations - MediaTek (mt76): - preparation for mt7996 Multi-Link Operation (MLO) support - Qualcomm/Atheros (ath12k): - continued work on MLO - Silabs (wfx): - Wake-on-WLAN support - Bluetooth: - add support for skb TX SND/COMPLETION timestamping - hci_core: enable buffer flow control for SCO/eSCO - coredump: log devcd dumps into the monitor - Bluetooth drivers: - intel: add support to configure TX power - nxp: handle bootloader error during cmd5 and cmd7" * tag 'net-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1681 commits) unix: fix up for "apparmor: add fine grained af_unix mediation" mctp: Fix incorrect tx flow invalidation condition in mctp-i2c net: usb: asix: ax88772: Increase phy_name size net: phy: Introduce PHY_ID_SIZE — minimum size for PHY ID string net: libwx: fix Tx L4 checksum net: libwx: fix Tx descriptor content for some tunnel packets atm: Fix NULL pointer dereference net: tn40xx: add pci-id of the aqr105-based Tehuti TN4010 cards net: tn40xx: prepare tn40xx driver to find phy of the TN9510 card net: tn40xx: create swnode for mdio and aqr105 phy and add to mdiobus net: phy: aquantia: add essential functions to aqr105 driver net: phy: aquantia: search for firmware-name in fwnode net: phy: aquantia: add probe function to aqr105 for firmware loading net: phy: Add swnode support to mdiobus_scan gve: add XDP DROP and PASS support for DQ gve: update XDP allocation path support RX buffer posting gve: merge packet buffer size fields gve: update GQ RX to use buf_size gve: introduce config-based allocation for XDP gve: remove xdp_xsk_done and xdp_xsk_wakeup statistics ...
