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.

+Xilinx SD-FEC Driver
+====================
+
+Overview
+========
+
+This driver supports SD-FEC Integrated Block for Zynq |Ultrascale+ (TM)| RFSoCs.
+
+.. |Ultrascale+ (TM)| unicode:: Ultrascale+ U+2122
+   .. with trademark sign
+
+For a full description of SD-FEC core features, see the `SD-FEC Product Guide (PG256) <https://www.xilinx.com/cgi-bin/docs/ipdoc?c=sd_fec;v=latest;d=pg256-sdfec-integrated-block.pdf>`_
+
+This driver supports the following features:
+
+  - Retrieval of the Integrated Block configuration and status information
+  - Configuration of LDPC codes
+  - Configuration of Turbo decoding
+  - Monitoring errors
+
+Missing features, known issues, and limitations of the SD-FEC driver are as
+follows:
+
+  - Only allows a single open file handler to any instance of the driver at any time
+  - Reset of the SD-FEC Integrated Block is not controlled by this driver
+  - Does not support shared LDPC code table wraparound
+
+The device tree entry is described in:
+`linux-xlnx/Documentation/devicetree/bindings/misc/xlnx,sd-fec.txt <https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/misc/xlnx%2Csd-fec.txt>`_
+
+
+Modes of Operation
+------------------
+
+The driver works with the SD-FEC core in two modes of operation:
+
+  - Run-time configuration
+  - Programmable Logic (PL) initialization
+
+
+Run-time Configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+For Run-time configuration the role of driver is to allow the software application to do the following:
+
+	- Load the configuration parameters for either Turbo decode or LDPC encode or decode
+	- Activate the SD-FEC core
+	- Monitor the SD-FEC core for errors
+	- Retrieve the status and configuration of the SD-FEC core
+
+Programmable Logic (PL) Initialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For PL initialization, supporting logic loads configuration parameters for either
+the Turbo decode or LDPC encode or decode.  The role of the driver is to allow
+the software application to do the following:
+
+	- Activate the SD-FEC core
+	- Monitor the SD-FEC core for errors
+	- Retrieve the status and configuration of the SD-FEC core
+
+
+Driver Structure
+================
+
+The driver provides a platform device where the ``probe`` and ``remove``
+operations are provided.
+
+  - probe: Updates configuration register with device-tree entries plus determines the current activate state of the core, for example, is the core bypassed or has the core been started.
+
+
+The driver defines the following driver file operations to provide user
+application interfaces:
+
+  - open: Implements restriction that only a single file descriptor can be open per SD-FEC instance at any time
+  - release: Allows another file descriptor to be open, that is after current file descriptor is closed
+  - poll: Provides a method to monitor for SD-FEC Error events
+  - unlocked_ioctl: Provides the following ioctl commands that allows the application configure the SD-FEC core:
+
+		- :c:macro:`XSDFEC_START_DEV`
+		- :c:macro:`XSDFEC_STOP_DEV`
+		- :c:macro:`XSDFEC_GET_STATUS`
+		- :c:macro:`XSDFEC_SET_IRQ`
+		- :c:macro:`XSDFEC_SET_TURBO`
+		- :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+		- :c:macro:`XSDFEC_GET_CONFIG`
+		- :c:macro:`XSDFEC_SET_ORDER`
+		- :c:macro:`XSDFEC_SET_BYPASS`
+		- :c:macro:`XSDFEC_IS_ACTIVE`
+		- :c:macro:`XSDFEC_CLEAR_STATS`
+		- :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`
+
+
+Driver Usage
+============
+
+
+Overview
+--------
+
+After opening the driver, the user should find out what operations need to be
+performed to configure and activate the SD-FEC core and determine the
+configuration of the driver.
+The following outlines the flow the user should perform:
+
+  - Determine Configuration
+  - Set the order, if not already configured as desired
+  - Set Turbo decode, LPDC encode or decode parameters, depending on how the
+    SD-FEC core is configured plus if the SD-FEC has not been configured for PL
+    initialization
+  - Enable interrupts, if not already enabled
+  - Bypass the SD-FEC core, if required
+  - Start the SD-FEC core if not already started
+  - Get the SD-FEC core status
+  - Monitor for interrupts
+  - Stop the SD-FEC core
+
+
+Note: When monitoring for interrupts if a critical error is detected where a reset is required, the driver will be required to load the default configuration.
+
+
+Determine Configuration
+-----------------------
+
+Determine the configuration of the SD-FEC core by using the ioctl
+:c:macro:`XSDFEC_GET_CONFIG`.
+
+Set the Order
+-------------
+
+Setting the order determines how the order of Blocks can change from input to output.
+
+Setting the order is done by using the ioctl :c:macro:`XSDFEC_SET_ORDER`
+
+Setting the order can only be done if the following restrictions are met:
+
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+
+Add LDPC Codes
+--------------
+
+The following steps indicate how to add LDPC codes to the SD-FEC core:
+
+	- Use the auto-generated parameters to fill the :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>` for the desired LDPC code.
+	- Set the SC, QA, and LA table offsets for the LPDC parameters and the parameters in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+	- Set the desired Code Id value in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+	- Add the LPDC Code Parameters using the ioctl :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+	- For the applied LPDC Code Parameter use the function :c:func:`xsdfec_calculate_shared_ldpc_table_entry_size` to calculate the size of shared LPDC code tables. This allows the user to determine the shared table usage so when selecting the table offsets for the next LDPC code parameters unused table areas can be selected.
+	- Repeat for each LDPC code parameter.
+
+Adding LDPC codes can only be done if the following restrictions are met:
+
+	- The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as LDPC
+	- The ``code_wr_protect`` of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates that write protection is not enabled
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not started
+
+Set Turbo Decode
+----------------
+
+Configuring the Turbo decode parameters is done by using the ioctl :c:macro:`XSDFEC_SET_TURBO` using auto-generated parameters to fill the :c:type:`struct xsdfec_turbo <xsdfec_turbo>` for the desired Turbo code.
+
+Adding Turbo decode can only be done if the following restrictions are met:
+
+	- The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Enable Interrupts
+-----------------
+
+Enabling or disabling interrupts is done by using the ioctl :c:macro:`XSDFEC_SET_IRQ`. The members of the parameter passed, :c:type:`struct xsdfec_irq <xsdfec_irq>`, to the ioctl are used to set and clear different categories of interrupts. The category of interrupt is controlled as following:
+
+  - ``enable_isr`` controls the ``tlast`` interrupts
+  - ``enable_ecc_isr`` controls the ECC interrupts
+
+If the ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO then the enabling ECC errors is not required.
+
+Bypass the SD-FEC
+-----------------
+
+Bypassing the SD-FEC is done by using the ioctl :c:macro:`XSDFEC_SET_BYPASS`
+
+Bypassing the SD-FEC can only be done if the following restrictions are met:
+
+	- The ``state`` member of :c:type:`struct xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Start the SD-FEC core
+---------------------
+
+Start the SD-FEC core by using the ioctl :c:macro:`XSDFEC_START_DEV`
+
+Get SD-FEC Status
+-----------------
+
+Get the SD-FEC status of the device by using the ioctl :c:macro:`XSDFEC_GET_STATUS`, which will fill the :c:type:`struct xsdfec_status <xsdfec_status>`
+
+Monitor for Interrupts
+----------------------
+
+	- Use the poll system call to monitor for an interrupt. The poll system call waits for an interrupt to wake it up or times out if no interrupt occurs.
+	- On return Poll ``revents`` will indicate whether stats and/or state have been updated
+		- ``POLLPRI`` indicates a critical error and the user should use :c:macro:`XSDFEC_GET_STATUS` and :c:macro:`XSDFEC_GET_STATS` to confirm
+		- ``POLLRDNORM`` indicates a non-critical error has occurred and the user should use  :c:macro:`XSDFEC_GET_STATS` to confirm
+	- Get stats by using the ioctl :c:macro:`XSDFEC_GET_STATS`
+		- For critical error the ``isr_err_count`` or ``uecc_count`` member  of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+		- For non-critical errors the ``cecc_count`` member of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+	- Get state by using the ioctl :c:macro:`XSDFEC_GET_STATUS`
+		- For a critical error the ``state`` of :c:type:`xsdfec_status <xsdfec_status>` will indicate a Reset Is Required
+	- Clear stats by using the ioctl :c:macro:`XSDFEC_CLEAR_STATS`
+
+If a critical error is detected where a reset is required. The application is required to call the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`, after the reset and it is not required to call the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Note: Using poll system call prevents busy looping using :c:macro:`XSDFEC_GET_STATS` and :c:macro:`XSDFEC_GET_STATUS`
+
+Stop the SD-FEC Core
+---------------------
+
+Stop the device by using the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Set the Default Configuration
+-----------------------------
+
+Load default configuration by using the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG` to restore the driver.
+
+Limitations
+-----------
+
+Users should not duplicate SD-FEC device file handlers, for example fork() or dup() a process that has a created an SD-FEC file handler.
