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.

+	  Say Y here if your device has buttons or a simple joystick connected
+	  directly to GPIO lines. Your board-specific setup logic must also
+	  provide a platform device and platform data saying which GPIOs are
+	  used.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called gpio_mouse.

+config MOUSE_MAPLE
+	tristate "Maple mouse (for the Dreamcast)"
+	depends on MAPLE
+	help
+	  This driver supports the Maple mouse on the SEGA Dreamcast.
+
+	  Most Dreamcast users, who have a mouse, will say Y here.
+
+	  To compile this driver as a module choose M here: the module will be
+	  called maplemouse.
+
+config MOUSE_SYNAPTICS_I2C
+	tristate "Synaptics I2C Touchpad support"
+	depends on I2C
+	help
+	  This driver supports Synaptics I2C touchpad controller on eXeda
+	  mobile device.
+	  The device will not work the synaptics X11 driver because
+	  (i) it  reports only relative coordinates and has no capabilities
+	  to report absolute coordinates
+	  (ii) the eXeda device itself uses Xfbdev as X Server and it does
+	  not allow using xf86-input-* drivers.
+
+	  Say y here if you have eXeda device and want to use a Synaptics
+	  I2C Touchpad.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called synaptics_i2c.
+
+config MOUSE_SYNAPTICS_USB
+	tristate "Synaptics USB device support"
+	depends on USB_ARCH_HAS_HCD
+	select USB
+	help
+	  Say Y here if you want to use a Synaptics USB touchpad or pointing
+	  stick.
+
+	  While these devices emulate an USB mouse by default and can be used
+	  with standard usbhid driver, this driver, together with its X.Org
+	  counterpart, allows you to fully utilize capabilities of the device.
+	  More information can be found at:
+	  <http://jan-steinhoff.de/linux/synaptics-usb.html>
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called synaptics_usb.
+
+config MOUSE_NAVPOINT_PXA27x
+	tristate "Synaptics NavPoint (PXA27x SSP/SPI)"
+	depends on PXA27x && PXA_SSP
+	help
+	  This driver adds support for the Synaptics NavPoint touchpad connected
+	  to a PXA27x SSP port in SPI slave mode. The device emulates a mouse;
+	  a tap or tap-and-a-half drag gesture emulates the left mouse button.
+	  For example, use the xf86-input-evdev driver for an X pointing device.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called navpoint.
