Pull networking updates from Jakub Kicinski: "Core: - Enable memcg accounting for various networking objects. BPF: - Introduce bpf timers. - Add perf link and opaque bpf_cookie which the program can read out again, to be used in libbpf-based USDT library. - Add bpf_task_pt_regs() helper to access user space pt_regs in kprobes, to help user space stack unwinding. - Add support for UNIX sockets for BPF sockmap. - Extend BPF iterator support for UNIX domain sockets. - Allow BPF TCP congestion control progs and bpf iterators to call bpf_setsockopt(), e.g. to switch to another congestion control algorithm. Protocols: - Support IOAM Pre-allocated Trace with IPv6. - Support Management Component Transport Protocol. - bridge: multicast: add vlan support. - netfilter: add hooks for the SRv6 lightweight tunnel driver. - tcp: - enable mid-stream window clamping (by user space or BPF) - allow data-less, empty-cookie SYN with TFO_SERVER_COOKIE_NOT_REQD - more accurate DSACK processing for RACK-TLP - mptcp: - add full mesh path manager option - add partial support for MP_FAIL - improve use of backup subflows - optimize option processing - af_unix: add OOB notification support. - ipv6: add IFLA_INET6_RA_MTU to expose MTU value advertised by the router. - mac80211: Target Wake Time support in AP mode. - can: j1939: extend UAPI to notify about RX status. Driver APIs: - Add page frag support in page pool API. - Many improvements to the DSA (distributed switch) APIs. - ethtool: extend IRQ coalesce uAPI with timer reset modes. - devlink: control which auxiliary devices are created. - Support CAN PHYs via the generic PHY subsystem. - Proper cross-chip support for tag_8021q. - Allow TX forwarding for the software bridge data path to be offloaded to capable devices. Drivers: - veth: more flexible channels number configuration. - openvswitch: introduce per-cpu upcall dispatch. - Add internet mix (IMIX) mode to pktgen. - Transparently handle XDP operations in the bonding driver. - Add LiteETH network driver. - Renesas (ravb): - support Gigabit Ethernet IP - NXP Ethernet switch (sja1105): - fast aging support - support for "H" switch topologies - traffic termination for ports under VLAN-aware bridge - Intel 1G Ethernet - support getcrosststamp() with PCIe PTM (Precision Time Measurement) for better time sync - support Credit-Based Shaper (CBS) offload, enabling HW traffic prioritization and bandwidth reservation - Broadcom Ethernet (bnxt) - support pulse-per-second output - support larger Rx rings - Mellanox Ethernet (mlx5) - support ethtool RSS contexts and MQPRIO channel mode - support LAG offload with bridging - support devlink rate limit API - support packet sampling on tunnels - Huawei Ethernet (hns3): - basic devlink support - add extended IRQ coalescing support - report extended link state - Netronome Ethernet (nfp): - add conntrack offload support - Broadcom WiFi (brcmfmac): - add WPA3 Personal with FT to supported cipher suites - support 43752 SDIO device - Intel WiFi (iwlwifi): - support scanning hidden 6GHz networks - support for a new hardware family (Bz) - Xen pv driver: - harden netfront against malicious backends - Qualcomm mobile - ipa: refactor power management and enable automatic suspend - mhi: move MBIM to WWAN subsystem interfaces Refactor: - Ambient BPF run context and cgroup storage cleanup. - Compat rework for ndo_ioctl. Old code removal: - prism54 remove the obsoleted driver, deprecated by the p54 driver. - wan: remove sbni/granch driver" * tag 'net-next-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1715 commits) net: Add depends on OF_NET for LiteX's LiteETH ipv6: seg6: remove duplicated include net: hns3: remove unnecessary spaces net: hns3: add some required spaces net: hns3: clean up a type mismatch warning net: hns3: refine function hns3_set_default_feature() ipv6: remove duplicated 'net/lwtunnel.h' include net: w5100: check return value after calling platform_get_resource() net/mlxbf_gige: Make use of devm_platform_ioremap_resourcexxx() net: mdio: mscc-miim: Make use of the helper function devm_platform_ioremap_resource() net: mdio-ipq4019: Make use of devm_platform_ioremap_resource() fou: remove sparse errors ipv4: fix endianness issue in inet_rtm_getroute_build_skb() octeontx2-af: Set proper errorcode for IPv4 checksum errors octeontx2-af: Fix static code analyzer reported issues octeontx2-af: Fix mailbox errors in nix_rss_flowkey_cfg octeontx2-af: Fix loop in free and unmap counter af_unix: fix potential NULL deref in unix_dgram_connect() dpaa2-eth: Replace strlcpy with strscpy octeontx2-af: Use NDC TX for transmit packet data ...
