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.

+68060 INTEGER SOFTWARE PACKAGE (Kernel version)
+------------------------------------------------
+
+The file isp.sa contains the 68060 Integer Software Package.
+This package is essentially an exception handler that can be
+integrated into an operating system to handle the "Unimplemented
+Integer Instruction" exception vector #61.
+This exception is taken when any of the integer instructions
+not hardware implemented on the 68060 are encountered. The
+isp.sa provides full emulation support for these instructions.
+
+The unimplemented integer instructions are:
+	64-bit divide
+	64-bit multiply
+	movep
+	cmp2
+	chk2
+	cas (w/ a misaligned effective address)
+	cas2
+
+Release file format:
+--------------------
+The file isp.sa is essentially a hexadecimal image of the
+release package. This is the ONLY format which will be supported.
+The hex image was created by assembling the source code and
+then converting the resulting binary output image into an
+ASCII text file. The hexadecimal numbers are listed
+using the Motorola Assembly Syntax assembler directive "dc.l"
+(define constant longword). The file can be converted to other
+assembly syntaxes by using any word processor with a global
+search and replace function.
+
+To assist in assembling and linking this module with other modules,
+the installer should add a symbolic label to the top of the file.
+This will allow calling routines to access the entry points
+of this package.
+
+The source code isp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+
+(top of module)
+	-----------------
+	|		| - 128 byte-sized section
+   (1)  |   Call-Out    | - 4 bytes per entry (user fills these in)
+	|		| - example routines in iskeleton.s
+	-----------------
+	|		| - 8 bytes per entry
+   (2)  | Entry Point   | - user does a "bra" or "jmp" to this address
+	|               |
+	-----------------
+	|		| - code section
+   (3)  ~		~
+	|		|
+	-----------------
+(bottom of module)
+
+The first section of this module is the "Call-out" section. This section
+is NOT INCLUDED in isp.sa (an example "Call-out" section is provided at
+the end of the file iskeleton.s). The purpose of this section is to allow
+the ISP routines to reference external functions that must be provided
+by the host operating system. This section MUST be exactly 128 bytes in
+size. There are 32 fields, each 4 bytes in size. Each field corresponds
+to a function required by the ISP (these functions and their location are
+listed in "68060ISP call-outs" below). Each field entry should contain
+the address of the corresponding function RELATIVE to the starting address
+of the "call-out" section. The "Call-out" section must sit adjacent to the
+isp.sa image in memory.
+
+The second section, the "Entry-point" section, is used by external routines
+to access the functions within the ISP. Since the isp.sa hex file contains
+no symbol names, this section contains function entry points that are fixed
+with respect to the top of the package. The currently defined entry-points
+are listed in section "68060 ISP entry points" below. A calling routine
+would simply execute a "bra" or "jmp" that jumped to the selected function
+entry-point.
+
+For example, if the 68060 hardware took a "Unimplemented Integer Instruction"
+exception (vector #61), the operating system should execute something
+similar to:
+
+	bra	_060ISP_TOP+128+0
+
+(_060ISP_TOP is the starting address of the "Call-out" section; the "Call-out"
+section is 128 bytes long; and the Unimplemented Integer ISP handler entry
+point is located 0 bytes from the top of the "Entry-point" section.)
+
+The third section is the code section. After entering through an "Entry-point",
+the entry code jumps to the appropriate emulation code within the code section.

+0x038:	_060_isp_cas_restart
+
+Integrating cas/cas2:
+---------------------
+The instructions "cas2" and "cas" (when used with a misaligned effective
+address) take the Unimplemented Integer Instruction exception. When the
+060ISP is installed properly, these instructions will enter through the
+_060_isp_unimp() entry point of the ISP.
+
+After the 060ISP decodes the instruction type and fetches the appropriate
+data registers, and BEFORE the actual emulated transfers occur, the
+package calls either the "Call-out" _060_real_cas() or _060_real_cas2().
+If the emulation code provided by the 060ISP is sufficient for the
+host system (see isp.s source code), then these "Call-out"s should be
+made, by the system integrator, to point directly back into the package
+through the "Entry-point"s _060_isp_cas() or _060_isp_cas2().
+
+One other necessary action by the integrator is to supply the routines
+_060_real_lock_page() and _060_real_unlock_page(). These functions are
+defined further in iskeleton.s and the 68060 Software Package Specification.
+
+If the "core" emulation routines of either "cas" or "cas2" perform some
+actions which are too system-specific, then the system integrator must
+supply new emulation code. This new emulation code should reside within
+the functions _060_real_cas() or _060_real_cas2(). When this new emulation
+code has completed, then it should re-enter the 060ISP package through the
+"Entry-point" _060_isp_cas_finish() or _060_isp_cas2_finish().
+To see what the register state is upon entering _060_real_cas() or
+_060_real_cas2() and what it should be upon return to the package through
+_060_isp_cas_finish() or _060_isp_cas2_finish(), please refer to the
+source code in isp.s.
