Merge tag 'net-next-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "Core: - Remove socket skb caches - Add a SO_RESERVE_MEM socket op to forward allocate buffer space and avoid memory accounting overhead on each message sent - Introduce managed neighbor entries - added by control plane and resolved by the kernel for use in acceleration paths (BPF / XDP right now, HW offload users will benefit as well) - Make neighbor eviction on link down controllable by userspace to work around WiFi networks with bad roaming implementations -

Introduce bpf_get_branch_snapshot() to capture Last Branch Records - Implement variadic trace_printk helper - Add a new Bloomfilter map type - Track <8-byte scalar spill and refill - Access hw timestamp through BPF's __sk_buff - Disallow unprivileged BPF by default - Document BPF licensing Netfilter: - Introduce egress hook for looking at raw outgoing packets - Allow matching on and modifying inner headers / payload data - Add NFT_META_IFTYPE to match on the interface type either from ingress or egress Protocols: - Multi-Path TCP: - increase default max additional subflows to 2 - rework forward memory allocation - add getsockopts: MPTCP_INFO, MPTCP_TCPINFO, MPTCP_SUBFLOW_ADDRS - MCTP flow support allowing lower layer drivers to configure msg muxing as needed - Automatic Multicast Tunneling (AMT) driver based on RFC7450 - HSR support the redbox supervision frames (IEC-62439-3:2018) - Support for the ip6ip6 encapsulation of IOAM - Netlink interface for CAN-FD's Transmitter Delay Compensation -

support for Realtek RTL8365MB-VC, a 4+1 port 10M/100M/1GE switch - Mellanox Ethernet/IB switch (mlxsw) - multi-level qdisc hierarchy offload (e.g. RED, prio and shaping) - offload root TBF qdisc as port shaper - support multiple routing interface MAC address prefixes - support for IP-in-IP with IPv6 underlay - MediaTek WiFi (mt76) - mt7921 - ASPM, 6GHz, SDIO and testmode support - mt7915 - LED and TWT support -

Qualcomm phone SoC WiFi (wcn36xx) - enable Idle Mode Power Save (IMPS) to reduce power consumption during idle - Bluetooth driver support for MediaTek MT7922 and MT7921 - Enable support for AOSP Bluetooth extension in Qualcomm WCN399x and Realtek 8822C/8852A - Microsoft vNIC driver (mana) - support hibernation and kexec - Google vNIC driver (gve) - support for jumbo frames - implement Rx page reuse Refactor: - Make all writes to netdev->dev_addr go thru helpers, so that we can add this address to the address rbtree and handle the updates - Various TCP cleanups and optimizations including improvements to CPU cache use - Simplify the gnet_stats, Qdisc stats' handling and remove qdisc->running sequence counter - Driver changes and API updates to address devlink locking deficiencies" * tag 'net-next-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2122 commits) Revert "net: avoid double accounting for pure zerocopy skbs" selftests: net: add arp_ndisc_evict_nocarrier net: ndisc: introduce ndisc_evict_nocarrier sysctl parameter net: arp: introduce arp_evict_nocarrier sysctl parameter libbpf: Deprecate AF_XDP support kbuild: Unify options for BTF generation for vmlinux and modules selftests/bpf: Add a testcase for 64-bit bounds propagation issue. bpf: Fix propagation of signed bounds from 64-bit min/max into 32-bit. bpf: Fix propagation of bounds from 64-bit min/max into 32-bit and var_off. net: vmxnet3: remove multiple false checks in vmxnet3_ethtool.c net: avoid double accounting for pure zerocopy skbs tcp: rename sk_wmem_free_skb netdevsim: fix uninit value in nsim_drv_configure_vfs() selftests/bpf: Fix also no-alu32 strobemeta selftest bpf: Add missing map_delete_elem method to bloom filter map selftests/bpf: Add bloom map success test for userspace calls bpf: Add alignment padding for "map_extra" + consolidate holes bpf: Bloom filter map naming fixups selftests/bpf: Add test cases for struct_ops prog bpf: Add dummy BPF STRUCT_OPS for test purpose ...
