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.

+XILINX AXI ETHERNET Device Tree Bindings
+--------------------------------------------------------
+
+Also called  AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
+provides connectivity to an external ethernet PHY supporting different
+interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
+segments of memory for buffering TX and RX, as well as the capability of
+offloading TX/RX checksum calculation off the processor.
+
+Management configuration is done through the AXI interface, while payload is
+sent and received through means of an AXI DMA controller. This driver
+includes the DMA driver code, so this driver is incompatible with AXI DMA
+driver.
+
+For more details about mdio please refer phy.txt file in the same directory.
+
+Required properties:
+- compatible	: Must be one of "xlnx,axi-ethernet-1.00.a",
+		  "xlnx,axi-ethernet-1.01.a", "xlnx,axi-ethernet-2.01.a"
+- reg		: Address and length of the IO space, as well as the address
+                  and length of the AXI DMA controller IO space, unless
+                  axistream-connected is specified, in which case the reg
+                  attribute of the node referenced by it is used.
+- interrupts	: Should be a list of 2 or 3 interrupts: TX DMA, RX DMA,
+		  and optionally Ethernet core. If axistream-connected is
+		  specified, the TX/RX DMA interrupts should be on that node
+		  instead, and only the Ethernet core interrupt is optionally
+		  specified here.
+- phy-handle	: Should point to the external phy device if exists. Pointing
+		  this to the PCS/PMA PHY is deprecated and should be avoided.
+		  See ethernet.txt file in the same directory.
+- xlnx,rxmem	: Set to allocated memory buffer for Rx/Tx in the hardware
+
+Optional properties:
+- phy-mode	: See ethernet.txt
+- xlnx,phy-type	: Deprecated, do not use, but still accepted in preference
+		  to phy-mode.
+- xlnx,txcsum	: 0 or empty for disabling TX checksum offload,
+		  1 to enable partial TX checksum offload,
+		  2 to enable full TX checksum offload
+- xlnx,rxcsum	: Same values as xlnx,txcsum but for RX checksum offload
+- xlnx,switch-x-sgmii : Boolean to indicate the Ethernet core is configured to
+		  support both 1000BaseX and SGMII modes. If set, the phy-mode
+		  should be set to match the mode selected on core reset (i.e.
+		  by the basex_or_sgmii core input line).
+- clock-names: 	  Tuple listing input clock names. Possible clocks:
+		  s_axi_lite_clk: Clock for AXI register slave interface
+		  axis_clk: AXI4-Stream clock for TXD RXD TXC and RXS interfaces
+		  ref_clk: Ethernet reference clock, used by signal delay
+			   primitives and transceivers
+		  mgt_clk: MGT reference clock (used by optional internal
+			   PCS/PMA PHY)
+
+		  Note that if s_axi_lite_clk is not specified by name, the
+		  first clock of any name is used for this. If that is also not
+		  specified, the clock rate is auto-detected from the CPU clock
+		  (but only on platforms where this is possible). New device
+		  trees should specify all applicable clocks by name - the
+		  fallbacks to an unnamed clock or to CPU clock are only for
+		  backward compatibility.
+- clocks: 	  Phandles to input clocks matching clock-names. Refer to common
+		  clock bindings.
+- axistream-connected: Reference to another node which contains the resources
+		       for the AXI DMA controller used by this device.
+		       If this is specified, the DMA-related resources from that
+		       device (DMA registers and DMA TX/RX interrupts) rather
+		       than this one will be used.
+ - mdio		: Child node for MDIO bus. Must be defined if PHY access is
+		  required through the core's MDIO interface (i.e. always,
+		  unless the PHY is accessed through a different bus).
+		  Non-standard MDIO bus frequency is supported via
+		  "clock-frequency", see mdio.yaml.
+
+ - pcs-handle: 	  Phandle to the internal PCS/PMA PHY in SGMII or 1000Base-X
+		  modes, where "pcs-handle" should be used to point
+		  to the PCS/PMA PHY, and "phy-handle" should point to an
+		  external PHY if exists.
+

+		device_type = "network";
