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.

+* Device tree bindings for Texas instruments AEMIF controller
+
+The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
+provide a glue-less interface to a variety of asynchronous memory devices like
+ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
+can be accessed at any given time via four chip selects with 64M byte access
+per chip select. Synchronous memories such as DDR1 SD RAM, SDR SDRAM
+and Mobile SDR are not supported.
+
+Documentation:
+Davinci DM646x - http://www.ti.com/lit/ug/sprueq7c/sprueq7c.pdf

+
+Required properties:
+
+- compatible:		"ti,davinci-aemif"
+			"ti,keystone-aemif"
+			"ti,da850-aemif"
+
+- reg:			contains offset/length value for AEMIF control registers
+			space.
+
+- #address-cells:	Must be 2. The partition number has to be encoded in the
+			first address cell and it may accept values 0..N-1
+			(N - total number of partitions). It's recommended to
+			assign N-1 number for the control partition. The second
+			cell is the offset into the partition.
+
+- #size-cells:		Must be set to 1.
+
+- ranges:		Contains memory regions. There are two types of
+			ranges/partitions:
+			- CS-specific partition/range. If continuous, must be
+			set up to reflect the memory layout for 4 chipselects,
+			if not then additional range/partition can be added and
+			child device can select the proper one.
+			- control partition which is common for all CS
+			interfaces.
+
+- clocks:		the clock feeding the controller clock. Required only
+			if clock tree data present in device tree.
+			See clock-bindings.txt
+
+- clock-names:		clock name. It has to be "aemif". Required only if clock
+			tree data present in device tree, in another case don't
+			use it.
+			See clock-bindings.txt
+
+- clock-ranges:		Empty property indicating that child nodes can inherit
+			named clocks. Required only if clock tree data present
+			in device tree.
+			See clock-bindings.txt
+
+
+Child chip-select (cs) nodes contain the memory devices nodes connected to
+such as NOR (e.g. cfi-flash) and NAND (ti,davinci-nand, see davinci-nand.txt).
+There might be board specific devices like FPGAs.
+
+Required child cs node properties:
+
+- #address-cells:	Must be 2.
+
+- #size-cells:		Must be 1.
+
+- ranges:		Empty property indicating that child nodes can inherit
+			memory layout.
+
+- clock-ranges:		Empty property indicating that child nodes can inherit
+			named clocks. Required only if clock tree data present
+			in device tree.
+
+- ti,cs-chipselect:	number of chipselect. Indicates on the aemif driver
+			which chipselect is used for accessing the memory. For
+			compatibles "ti,davinci-aemif" and "ti,keystone-aemif"
+			it can be in range [0-3]. For compatible
+			"ti,da850-aemif" range is [2-5].
+
+Optional child cs node properties:
+
+- ti,cs-bus-width:		width of the asynchronous device's data bus
+				8 or 16 if not preset 8
+
+- ti,cs-select-strobe-mode:	enable/disable select strobe mode
+				In select strobe mode chip select behaves as
+				the strobe and is active only during the strobe
+				period. If present then enable.
+
+- ti,cs-extended-wait-mode:	enable/disable extended wait mode
+				if set, the controller monitors the EMIFWAIT pin
+				mapped to that chip select to determine if the
+				device wants to extend the strobe period. If
+				present then enable.
+
+- ti,cs-min-turnaround-ns:	minimum turn around time, ns
+				Time between the end of one asynchronous memory
+				access and the start of another asynchronous
+				memory access. This delay is not incurred
+				between a read followed by read or a write
+				followed by a write to same chip select.
+
+- ti,cs-read-setup-ns:		read setup width, ns
+				Time between the beginning of a memory cycle
+				and the activation of read strobe.
+				Minimum value is 1 (0 treated as 1).
+
+- ti,cs-read-strobe-ns:		read strobe width, ns
+				Time between the activation and deactivation of
+				the read strobe.
+				Minimum value is 1 (0 treated as 1).
+
+- ti,cs-read-hold-ns:		read hold width, ns
+				Time between the deactivation of the read
+				strobe and the end of the cycle (which may be
+				either an address change or the deactivation of
+				the chip select signal.
+				Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-setup-ns:		write setup width, ns
+				Time between the beginning of a memory cycle
+				and the activation of write strobe.
+				Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-strobe-ns:	write strobe width, ns
+				Time between the activation and deactivation of
+				the write strobe.
+				Minimum value is 1 (0 treated as 1).
+
+- ti,cs-write-hold-ns:		write hold width, ns
+				Time between the deactivation of the write
+				strobe and the end of the cycle (which may be
+				either an address change or the deactivation of
+				the chip select signal.
+				Minimum value is 1 (0 treated as 1).
+
+If any of the above parameters are absent, current parameter value will be taken
+from the corresponding HW reg.
