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 FLOATING-POINT SOFTWARE PACKAGE (Library version)
+--------------------------------------------------------
+
+The file fplsp.sa contains the "Library version" of the
+68060SP Floating-Point Software Package. The routines
+included in this module can be used to emulate the
+FP instructions not implemented in 68060 hardware. These
+instructions normally take exception vector #11
+"FP Unimplemented Instruction".
+
+By re-compiling a program that uses these instructions, and
+making subroutine calls in place of the unimplemented
+instructions, a program can avoid the overhead associated
+with taking the exception.
+
+Release file format:
+--------------------
+The file fplsp.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 fplsp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+The file fplsp.sa contains an "Entry-Point" section and a
+code section. The FPLSP has no "Call-Out" section. The first section
+is the "Entry-Point" section. In order to access a function in the
+package, a program must "bsr" or "jsr" to the location listed
+below in "68060FPLSP entry points" that corresponds to the desired
+function. A branch instruction located at the selected entry point
+within the package will then enter the correct emulation code routine.
+
+The entry point addresses at the beginning of the package will remain
+fixed so that a program calling the routines will not have to be
+re-compiled with every new 68060FPLSP release.
+
+There are 3 entry-points for each instruction type: single precision,
+double precision, and extended precision.
+
+As an example, the "fsin" library instruction can be passed an
+extended precision operand if program executes:
+
+# fsin.x fp0
+
+	fmovm.x	&0x01,-(%sp)	# pass operand on stack
+	bsr.l	_060FPLSP_TOP+0x1a8 # branch to fsin routine
+	add.l	&0xc,%sp	# clear operand from stack
+
+Upon return, fp0 holds the correct result. The FPSR is
+set correctly. The FPCR is unchanged. The FPIAR is undefined.
+
+Another example. This time, a dyadic operation:
+
+# frem.s %fp1,%fp0
+
+	fmov.s	%fp1,-(%sp)	# pass src operand
+	fmov.s	%fp0,-(%sp)	# pass dst operand
+	bsr.l	_060FPLSP_TOP+0x168 # branch to frem routine
+	addq.l	&0x8,%sp	# clear operands from stack
+
+Again, the result is returned in fp0. Note that BOTH operands
+are passed in single precision format.
+
+Exception reporting:
+--------------------
+The package takes exceptions according to the FPCR value upon subroutine
+entry. If an exception should be reported, then the package forces
+this exception using implemented floating-point instructions.
+For example, if the instruction being emulated should cause a
+floating-point Operand Error exception, then the library routine
+executes an FMUL of a zero and an infinity to force the OPERR
+exception. Although the FPIAR will be undefined for the enabled
+Operand Error exception handler, the user will at least be able
+to record that the event occurred.
+
+Miscellaneous:
+--------------
+The package does not attempt to correctly emulate instructions
+with Signalling NAN inputs. Use of SNANs should be avoided with
+this package.
+
+The fabs/fadd/fdiv/fint/fintrz/fmul/fneg/fsqrt/fsub entry points
+are provided for the convenience of older compilers that make
+subroutine calls for all fp instructions. The code does NOT emulate
+the instruction but rather simply executes it.
