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.

+	tristate "Parallel port support"
+	depends on HAS_IOMEM
+	help
+	  If you want to use devices connected to your machine's parallel port
+	  (the connector at the computer with 25 holes), e.g. printer, ZIP
+	  drive, PLIP link (Parallel Line Internet Protocol is mainly used to
+	  create a mini network by connecting the parallel ports of two local
+	  machines) etc., then you need to say Y here; please read
+	  <file:Documentation/admin-guide/parport.rst> and
+	  <file:drivers/parport/BUGS-parport>.
+
+	  For extensive information about drivers for many devices attaching
+	  to the parallel port see <http://www.torque.net/linux-pp.html> on
+	  the WWW.
+
+	  It is possible to share a single parallel port among several devices
+	  and it is safe to compile all the corresponding drivers into the
+	  kernel. To compile parallel port support as a module, choose M here:
+	  the module will be called parport.
+	  If you have more than one parallel port and want to specify which
+	  port and IRQ to be used by this driver at module load time, take a
+	  look at <file:Documentation/admin-guide/parport.rst>.
+
+	  If unsure, say Y.
+

+
+config PARPORT_PC
+	tristate "PC-style hardware"
+	depends on ARCH_MIGHT_HAVE_PC_PARPORT || (PCI && !S390)
+	help
+	  You should say Y here if you have a PC-style parallel port. All
+	  IBM PC compatible computers and some Alphas have PC-style
+	  parallel ports.  PA-RISC owners should only say Y here if they
+	  have a SuperIO parallel port.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called parport_pc.
+
+	  If unsure, say Y.

+	  This adds support for multi-IO PCI cards that have parallel and
+	  serial ports.  You should say Y or M here.  If you say M, the module
+	  will be called parport_serial.
+
+config PARPORT_PC_FIFO
+	bool "Use FIFO/DMA if available"
+	depends on PARPORT_PC
+	help
+	  Many parallel port chipsets provide hardware that can speed up
+	  printing. Say Y here if you want to take advantage of that.
+
+	  As well as actually having a FIFO, or DMA capability, the kernel
+	  will need to know which IRQ the parallel port has.  By default,
+	  parallel port interrupts will not be used, and so neither will the
+	  FIFO.  See <file:Documentation/admin-guide/parport.rst> to find out how to
+	  specify which IRQ/DMA to use.
+
+config PARPORT_PC_SUPERIO
+	bool "SuperIO chipset support"
+	depends on ARCH_MIGHT_HAVE_PC_PARPORT && PARPORT_PC && !PARISC

+	  SGI O2 machines. This code is also available as a module (say M),
+	  called parport_ip32.  If in doubt, saying N is the safe plan.
+
+config PARPORT_AMIGA
+	tristate "Amiga builtin port"
+	depends on AMIGA
+	select PARPORT_NOT_PC
+	help
+	  Say Y here if you need support for the parallel port hardware on

+	help
+	  Say Y here if you need parallel port support for the MFC3 card.
+	  This code is also available as a module (say M), called
+	  parport_mfc3. If in doubt, saying N is the safe plan.
+
+config PARPORT_ATARI
+	tristate "Atari hardware"
+	depends on ATARI
+	select PARPORT_NOT_PC

+	bool "IEEE 1284 transfer modes"
+	help
+	  If you have a printer that supports status readback or device ID, or
+	  want to use a device that uses enhanced parallel port transfer modes
+	  such as EPP and ECP, say Y here to enable advanced IEEE 1284
+	  transfer modes. Also say Y if you want device ID information to
