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. New hardware / drivers: - Ethernet: - nVidia BlueField-3 support (control traffic driver) - Ethernet support for imx93 SoCs - Motorcomm yt8531 gigabit Ethernet PHY - onsemi NCN26000 10BASE-T1S PHY (with support for PLCA) - Microchip LAN8841 PHY (incl. cable diagnostics and PTP) - Amlogic gxl MDIO mux - WiFi: - RealTek RTL8188EU (rtl8xxxu) - Qualcomm Wi-Fi 7 devices (ath12k) - CAN: - Renesas R-Car V4H Drivers: - Bluetooth: - Set Per Platform Antenna Gain (PPAG) for Intel controllers. - Ethernet NICs: - Intel (1G, igc): - support TSN / Qbv / packet scheduling features of i226 model - Intel (100G, ice): - use GNSS subsystem instead of TTY - multi-buffer XDP support - extend support for GPIO pins to E823 devices - nVidia/Mellanox: - update the shared buffer configuration on PFC commands - implement PTP adjphase function for HW offset control - TC support for Geneve and GRE with VF tunnel offload - more efficient crypto key management method - multi-port eswitch support - Netronome/Corigine: - add DCB IEEE support - support IPsec offloading for NFP3800 - Freescale/NXP (enetc): - support XDP_REDIRECT for XDP non-linear buffers - improve reconfig, avoid link flap and waiting for idle - support MAC Merge layer - Other NICs: - sfc/ef100: add basic devlink support for ef100 - ionic: rx_push mode operation (writing descriptors via MMIO) - bnxt: use the auxiliary bus abstraction for RDMA - r8169: disable ASPM and reset bus in case of tx timeout - cpsw: support QSGMII mode for J721e CPSW9G - cpts: support pulse-per-second output - ngbe: add an mdio bus driver - usbnet: optimize usbnet_bh() by avoiding unnecessary queuing - r8152: handle devices with FW with NCM support - amd-xgbe: support 10Mbps, 2.5GbE speeds and rx-adaptation - virtio-net: support multi buffer XDP - virtio/vsock: replace virtio_vsock_pkt with sk_buff - tsnep: XDP support - Ethernet high-speed switches: - nVidia/Mellanox (mlxsw): - add support for latency TLV (in FW control messages) - Microchip (sparx5): - separate explicit and implicit traffic forwarding rules, make the implicit rules always active - add support for egress DSCP rewrite - IS0 VCAP support (Ingress Classification) - IS2 VCAP filters (protos, L3 addrs, L4 ports, flags, ToS etc.) - ES2 VCAP support (Egress Access Control) - support for Per-Stream Filtering and Policing (802.1Q, 8.6.5.1) - Ethernet embedded switches: - Marvell (mv88e6xxx): - add MAB (port auth) offload support - enable PTP receive for mv88e6390 - NXP (ocelot): - support MAC Merge layer - support for the the vsc7512 internal copper phys - Microchip: - lan9303: convert to PHYLINK - lan966x: support TC flower filter statistics - lan937x: PTP support for KSZ9563/KSZ8563 and LAN937x - lan937x: support Credit Based Shaper configuration - ksz9477: support Energy Efficient Ethernet - other: - qca8k: convert to regmap read/write API, use bulk operations - rswitch: Improve TX timestamp accuracy - Intel WiFi (iwlwifi): - EHT (Wi-Fi 7) rate reporting - STEP equalizer support: transfer some STEP (connection to radio on platforms with integrated wifi) related parameters from the BIOS to the firmware. - Qualcomm 802.11ax WiFi (ath11k): - IPQ5018 support - Fine Timing Measurement (FTM) responder role support - channel 177 support - MediaTek WiFi (mt76): - per-PHY LED support - mt7996: EHT (Wi-Fi 7) support - Wireless Ethernet Dispatch (WED) reset support - switch to using page pool allocator - RealTek WiFi (rtw89): - support new version of Bluetooth co-existance - Mobile: - rmnet: support TX aggregation" * tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1872 commits) page_pool: add a comment explaining the fragment counter usage net: ethtool: fix __ethtool_dev_mm_supported() implementation ethtool: pse-pd: Fix double word in comments xsk: add linux/vmalloc.h to xsk.c sefltests: netdevsim: wait for devlink instance after netns removal selftest: fib_tests: Always cleanup before exit net/mlx5e: Align IPsec ASO result memory to be as required by hardware net/mlx5e: TC, Set CT miss to the specific ct action instance net/mlx5e: Rename CHAIN_TO_REG to MAPPED_OBJ_TO_REG net/mlx5: Refactor tc miss handling to a single function net/mlx5: Kconfig: Make tc offload depend on tc skb extension net/sched: flower: Support hardware miss to tc action net/sched: flower: Move filter handle initialization earlier net/sched: cls_api: Support hardware miss to tc action net/sched: Rename user cookie and act cookie sfc: fix builds without CONFIG_RTC_LIB sfc: clean up some inconsistent indentings net/mlx4_en: Introduce flexible array to silence overflow warning net: lan966x: Fix possible deadlock inside PTP net/ulp: Remove redundant ->clone() test in inet_clone_ulp(). ...

+Using the Digital TV Framework
+==============================
+
+Introduction
+~~~~~~~~~~~~
+
+One significant difference between Digital TV and Analogue TV that the
+unwary (like myself) should consider is that, although the component
+structure of DVB-T cards are substantially similar to Analogue TV cards,
+they function in substantially different ways.
+
+The purpose of an Analogue TV is to receive and display an Analogue
+Television signal. An Analogue TV signal (otherwise known as composite
+video) is an analogue encoding of a sequence of image frames (25 frames
+per second in Europe) rasterised using an interlacing technique.
+Interlacing takes two fields to represent one frame. Therefore, an
+Analogue TV card for a PC has the following purpose:
+
+* Tune the receiver to receive a broadcast signal
+* demodulate the broadcast signal
+* demultiplex the analogue video signal and analogue audio
+ signal.
+
+ .. note::
+
+ some countries employ a digital audio signal
+ embedded within the modulated composite analogue signal -
+ using NICAM signaling.)
+
+* digitize the analogue video signal and make the resulting datastream
+ available to the data bus.
+
+The digital datastream from an Analogue TV card is generated by
+circuitry on the card and is often presented uncompressed. For a PAL TV
+signal encoded at a resolution of 768x576 24-bit color pixels over 25
+frames per second - a fair amount of data is generated and must be
+processed by the PC before it can be displayed on the video monitor
+screen. Some Analogue TV cards for PCs have onboard MPEG2 encoders which
+permit the raw digital data stream to be presented to the PC in an
+encoded and compressed form - similar to the form that is used in
+Digital TV.
+
+The purpose of a simple budget digital TV card (DVB-T,C or S) is to
+simply:
+
+* Tune the received to receive a broadcast signal. * Extract the encoded
+ digital datastream from the broadcast signal.
+* Make the encoded digital datastream (MPEG2) available to the data bus.
+
+The significant difference between the two is that the tuner on the
+analogue TV card spits out an Analogue signal, whereas the tuner on the
+digital TV card spits out a compressed encoded digital datastream. As
+the signal is already digitised, it is trivial to pass this datastream
+to the PC databus with minimal additional processing and then extract
+the digital video and audio datastreams passing them to the appropriate
+software or hardware for decoding and viewing.
+
+Getting the card going
+~~~~~~~~~~~~~~~~~~~~~~
+
+The Device Driver API for DVB under Linux will the following
+device nodes via the devfs filesystem:
+
+* /dev/dvb/adapter0/demux0
+* /dev/dvb/adapter0/dvr0
+* /dev/dvb/adapter0/frontend0
+
+The ``/dev/dvb/adapter0/dvr0`` device node is used to read the MPEG2
+Data Stream and the ``/dev/dvb/adapter0/frontend0`` device node is used
+to tune the frontend tuner module. The ``/dev/dvb/adapter0/demux0`` is
+used to control what programs will be received.
+
+Depending on the card's feature set, the Device Driver API could also
+expose other device nodes:
+
+* /dev/dvb/adapter0/ca0
+* /dev/dvb/adapter0/audio0
+* /dev/dvb/adapter0/net0
+* /dev/dvb/adapter0/osd0
+* /dev/dvb/adapter0/video0
+
+The ``/dev/dvb/adapter0/ca0`` is used to decode encrypted channels. The
+other device nodes are found only on devices that use the av7110
+driver, with is now obsoleted, together with the extra API whose such
+devices use.
+
+Receiving a digital TV channel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This section attempts to explain how it works and how this affects the
+configuration of a Digital TV card.
+
+On this example, we're considering tuning into DVB-T channels in
+Australia, at the Melbourne region.
+
+The frequencies broadcast by Mount Dandenong transmitters are,
+currently:
+
+Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
+
+=========== ===========
+Broadcaster Frequency
+=========== ===========
+Seven 177.500 Mhz
+SBS 184.500 Mhz
+Nine 191.625 Mhz
+Ten 219.500 Mhz
+ABC 226.500 Mhz
+Channel 31 557.625 Mhz
+=========== ===========
+
+The digital TV Scan utilities (like dvbv5-scan) have use a set of
+compiled-in defaults for various countries and regions. Those are
+currently provided as a separate package, called dtv-scan-tables. It's
+git tree is located at LinuxTV.org:
+
+ https://git.linuxtv.org/dtv-scan-tables.git/
+
+If none of the tables there suit, you can specify a data file on the
+command line which contains the transponder frequencies. Here is a
+sample file for the above channel transponders, in the old "channel"
+format::
+
+ # Data file for DVB scan program
+ #
+ # C Frequency SymbolRate FEC QAM
+ # S Frequency Polarisation SymbolRate FEC
+ # T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
+
+ T 177500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+ T 184500000 7MHz AUTO AUTO QAM64 8k 1/8 NONE
+ T 191625000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+ T 219500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+ T 226500000 7MHz AUTO AUTO QAM64 8k 1/16 NONE
+ T 557625000 7MHz AUTO AUTO QPSK 8k 1/16 NONE
+
+Nowadays, we prefer to use a newer format, with is more verbose and easier
+to understand. With the new format, the "Seven" channel transponder's
+data is represented by::
+
+ [Seven]
+ DELIVERY_SYSTEM = DVBT
+ FREQUENCY = 177500000
+ BANDWIDTH_HZ = 7000000
+ CODE_RATE_HP = AUTO
+ CODE_RATE_LP = AUTO
+ MODULATION = QAM/64
+ TRANSMISSION_MODE = 8K
+ GUARD_INTERVAL = 1/16
+ HIERARCHY = NONE
+ INVERSION = AUTO
+
+For an updated version of the complete table, please see:
+
+ https://git.linuxtv.org/dtv-scan-tables.git/tree/dvb-t/au-Melbourne
+
+When the Digital TV scanning utility runs, it will output a file
+containing the information for all the audio and video programs that
+exists into each channel's transponders which the card's frontend can
+lock onto. (i.e. any whose signal is strong enough at your antenna).
+
+Here's the output of the dvbv5 tools from a channel scan took from
