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.

+title: NVIDIA Tegra GPIO Controller (Tegra186 and later)
+

+
+description: |
+  Tegra186 contains two GPIO controllers; a main controller and an "AON"
+  controller. This binding document applies to both controllers. The register
+  layouts for the controllers share many similarities, but also some
+  significant differences. Hence, this document describes closely related but
+  different bindings and compatible values.
+
+  The Tegra186 GPIO controller allows software to set the IO direction of,
+  and read/write the value of, numerous GPIO signals. Routing of GPIO signals
+  to package balls is under the control of a separate pin controller hardware
+  block. Two major sets of registers exist:
+
+    a) Security registers, which allow configuration of allowed access to the
+       GPIO register set. These registers exist in a single contiguous block
+       of physical address space. The size of this block, and the security
+       features available, varies between the different GPIO controllers.
+
+       Access to this set of registers is not necessary in all circumstances.
+       Code that wishes to configure access to the GPIO registers needs access
+       to these registers to do so. Code which simply wishes to read or write
+       GPIO data does not need access to these registers.
+
+    b) GPIO registers, which allow manipulation of the GPIO signals. In some
+       GPIO controllers, these registers are exposed via multiple "physical
+       aliases" in address space, each of which access the same underlying
+       state. See the hardware documentation for rationale. Any particular
+       GPIO client is expected to access just one of these physical aliases.
+
+    Tegra HW documentation describes a unified naming convention for all GPIOs
+    implemented by the SoC. Each GPIO is assigned to a port, and a port may
+    control a number of GPIOs. Thus, each GPIO is named according to an
+    alphabetical port name and an integer GPIO name within the port. For
+    example, GPIO_PA0, GPIO_PN6, or GPIO_PCC3.
+
+    The number of ports implemented by each GPIO controller varies. The number
+    of implemented GPIOs within each port varies. GPIO registers within a
+    controller are grouped and laid out according to the port they affect.
+
+    The mapping from port name to the GPIO controller that implements that
+    port, and the mapping from port name to register offset within a
+    controller, are both extremely non-linear. The header file
+    <dt-bindings/gpio/tegra186-gpio.h> describes the port-level mapping. In
+    that file, the naming convention for ports matches the HW documentation.
+    The values chosen for the names are alphabetically sorted within a
+    particular controller. Drivers need to map between the DT GPIO IDs and HW
+    register offsets using a lookup table.
+
+    Each GPIO controller can generate a number of interrupt signals. Each
+    signal represents the aggregate status for all GPIOs within a set of
+    ports. Thus, the number of interrupt signals generated by a controller
+    varies as a rough function of the number of ports it implements. Note
+    that the HW documentation refers to both the overall controller HW
+    module and the sets-of-ports as "controllers".
+
+    Each GPIO controller in fact generates multiple interrupts signals for
+    each set of ports. Each GPIO may be configured to feed into a specific
+    one of the interrupt signals generated by a set-of-ports. The intent is
+    for each generated signal to be routed to a different CPU, thus allowing
+    different CPUs to each handle subsets of the interrupts within a port.
+    The status of each of these per-port-set signals is reported via a
+    separate register. Thus, a driver needs to know which status register to
+    observe. This binding currently defines no configuration mechanism for
+    this. By default, drivers should use register
+    GPIO_${port}_INTERRUPT_STATUS_G1_0. Future revisions to the binding could
+    define a property to configure this.
