Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted
Pull networking updates from Jakub Kicinski: "Core: - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols: - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

+TI PHY: DT DOCUMENTATION FOR PHYs in TI PLATFORMs
+
+OMAP CONTROL PHY
+
+Required properties:

+ "ti,control-phy-otghs" - if it has otghs_control mailbox register as on OMAP4.
+ "ti,control-phy-usb2" - if it has Power down bit in control_dev_conf register
+ e.g. USB2_PHY on OMAP5.
+ "ti,control-phy-pipe3" - if it has DPLL and individual Rx & Tx power control
+ e.g. USB3 PHY and SATA PHY on OMAP5.
+ "ti,control-phy-pcie" - for pcie to support external clock for pcie and to
+ set PCS delay value.
+ e.g. PCIE PHY in DRA7x
+ "ti,control-phy-usb2-dra7" - if it has power down register like USB2 PHY on
+ DRA7 platform.
+ "ti,control-phy-usb2-am437" - if it has power down register like USB2 PHY on
+ AM437 platform.
+ - reg : register ranges as listed in the reg-names property
+ - reg-names: "otghs_control" for control-phy-otghs
+ "power", "pcie_pcs" and "control_sma" for control-phy-pcie
+ "power" for all other types
+
+omap_control_usb: omap-control-usb@4a002300 {
+ compatible = "ti,control-phy-otghs";
+ reg = <0x4a00233c 0x4>;
+ reg-names = "otghs_control";
+};
+
+TI PIPE3 PHY
+
+Required properties:
+ - compatible: Should be "ti,phy-usb3", "ti,phy-pipe3-sata" or
+ "ti,phy-pipe3-pcie. "ti,omap-usb3" is deprecated.
+ - reg : Address and length of the register set for the device.
+ - reg-names: The names of the register addresses corresponding to the registers
+ filled in "reg".
+ - #phy-cells: determine the number of cells that should be given in the
+ phandle while referencing this phy.
+ - clocks: a list of phandles and clock-specifier pairs, one for each entry in
+ clock-names.
+ - clock-names: should include:
+ * "wkupclk" - wakeup clock.
