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.

+.TH BOOTGRAPH 8
+.SH NAME
+bootgraph \- Kernel boot timing analysis
+.SH SYNOPSIS
+.ft B
+.B bootgraph
+.RB [ OPTIONS ]
+.RB [ COMMAND ]
+.SH DESCRIPTION
+\fBbootgraph \fP reads the dmesg log from kernel boot and
+creates an html representation of the initcall timeline. It graphs
+every module init call found, through both kernel and user modes. The
+timeline is split into two phases: kernel mode & user mode. kernel mode
+represents a single process run on a single cpu with serial init calls.
+Once user mode begins, the init process is called, and the init calls
+start working in parallel.
+.PP
+If no specific command is given, the tool reads the current dmesg log and
+outputs a new timeline.
+.PP
+The tool can also augment the timeline with ftrace data on custom target
+functions as well as full trace callgraphs.
+.PP
+Generates output files in subdirectory: boot-yymmdd-HHMMSS
+   html timeline   :     <hostname>_boot.html
+   raw dmesg file  :     <hostname>_boot_dmesg.txt
+   raw ftrace file :     <hostname>_boot_ftrace.txt
+.SH OPTIONS
+.TP
+\fB-h\fR
+Print this help text
+.TP
+\fB-v\fR
+Print the current tool version
+.TP
+\fB-addlogs\fR
+Add the dmesg log to the html output. It will be viewable by
+clicking a button in the timeline.
+.TP
+\fB-result \fIfile\fR
+Export a results table to a text file for parsing.
+.TP
+\fB-o \fIname\fR
+Overrides the output subdirectory name when running a new test.
+Use {date}, {time}, {hostname} for current values.
+.sp
+e.g. boot-{hostname}-{date}-{time}
+.SS "advanced"
+.TP
+\fB-f or -callgraph\fR
+Use ftrace to create initcall callgraphs (default: disabled). If -func
+is not used there will be one callgraph per initcall. This can produce
+very large outputs, i.e. 10MB - 100MB.
+.TP
+\fB-fstat\fR
+Use ftrace to add function detail (default: disabled)
+.TP
+\fB-maxdepth \fIlevel\fR
+limit the callgraph trace depth to \fIlevel\fR (default: 2). This is
+the best way to limit the output size when using -callgraph.
+.TP
+\fB-mincg \fIt\fR
+Discard all callgraphs shorter than \fIt\fR milliseconds (default: 0=all).
+This reduces the html file size as there can be many tiny callgraphs
+which are barely visible in the timeline.
+The value is a float: e.g. 0.001 represents 1 us.
+.TP
+\fB-cgfilter \fI"func1,func2,..."\fR
+Reduce callgraph output in the timeline by limiting it to a list of calls. The
+argument can be a single function name or a comma delimited list.
+(default: none)
+.TP
+\fB-cgskip \fIfile\fR
+Reduce callgraph output in the timeline by skipping over uninteresting
+functions in the trace, e.g. printk or console_unlock. The functions listed
+in this file will show up as empty leaves in the callgraph with only the start/end
+times displayed.
+(default: none)
+.TP
+\fB-timeprec \fIn\fR
+Number of significant digits in timestamps (0:S, 3:ms, [6:us])
+.TP
+\fB-expandcg\fR
+pre-expand the callgraph data in the html output (default: disabled)
+.TP
+\fB-func \fI"func1,func2,..."\fR
+Instead of tracing each initcall, trace a custom list of functions (default: do_one_initcall)
+.TP
+\fB-reboot\fR
+Reboot the machine and generate a new timeline automatically. Works in 4 steps.
+  1. updates grub with the required kernel parameters
+  2. installs a cron job which re-runs the tool after reboot
+  3. reboots the system
+  4. after startup, extracts the data and generates the timeline
+.TP
+\fB-manual\fR
+Show the requirements to generate a new timeline manually. Requires 3 steps.
+  1. append the string to the kernel command line via your native boot manager.
+  2. reboot the system
+  3. after startup, re-run the tool with the same arguments and no command
+
+.SH COMMANDS
+.SS "rebuild"
+.TP
+\fB-dmesg \fIfile\fR
+Create HTML output from an existing dmesg file.
+.TP
+\fB-ftrace \fIfile\fR
+Create HTML output from an existing ftrace file (used with -dmesg).
+.SS "other"
+.TP
+\fB-flistall\fR
+Print all ftrace functions capable of being captured. These are all the
+possible values you can add to trace via the -func argument.
+.TP
+\fB-sysinfo\fR
+Print out system info extracted from BIOS. Reads /dev/mem directly instead of going through dmidecode.
