Pull networking updates from Paolo Abeni:
 "The most interesting thing is probably the networking structs
  reorganization and a significant amount of changes is around
  self-tests.

  Core & protocols:

   - Analyze and reorganize core networking structs (socks, netdev,
     netns, mibs) to optimize cacheline consumption and set up build
     time warnings to safeguard against future header changes

     This improves TCP performances with many concurrent connections up
     to 40%

   - Add page-pool netlink-based introspection, exposing the memory
     usage and recycling stats. This helps indentify bad PP users and
     possible leaks

   - Refine TCP/DCCP source port selection to no longer favor even
     source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
     lowers the time taken by connect() for hosts having many active
     connections to the same destination

   - Refactor the TCP bind conflict code, shrinking related socket
     structs

   - Refactor TCP SYN-Cookie handling, as a preparation step to allow
     arbitrary SYN-Cookie processing via eBPF

   - Tune optmem_max for 0-copy usage, increasing the default value to
     128KB and namespecifying it

   - Allow coalescing for cloned skbs coming from page pools, improving
     RX performances with some common configurations

   - Reduce extension header parsing overhead at GRO time

   - Add bridge MDB bulk deletion support, allowing user-space to
     request the deletion of matching entries

   - Reorder nftables struct members, to keep data accessed by the
     datapath first

   - Introduce TC block ports tracking and use. This allows supporting
     multicast-like behavior at the TC layer

   - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
     classifiers (RSVP and tcindex)

   - More data-race annotations

   - Extend the diag interface to dump TCP bound-only sockets

   - Conditional notification of events for TC qdisc class and actions

   - Support for WPAN dynamic associations with nearby devices, to form
     a sub-network using a specific PAN ID

   - Implement SMCv2.1 virtual ISM device support

   - Add support for Batman-avd mulicast packet type

  BPF:

   - Tons of verifier improvements:
       - BPF register bounds logic and range support along with a large
         test suite
       - log improvements
       - complete precision tracking support for register spills
       - track aligned STACK_ZERO cases as imprecise spilled registers.
         This improves the verifier "instructions processed" metric from
         single digit to 50-60% for some programs
       - support for user's global BPF subprogram arguments with few
         commonly requested annotations for a better developer
         experience
       - support tracking of BPF_JNE which helps cases when the compiler
         transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
         like
       - several fixes

   - Add initial TX metadata implementation for AF_XDP with support in
     mlx5 and stmmac drivers. Two types of offloads are supported right
     now, that is, TX timestamp and TX checksum offload

   - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
     kernel and from kernel into BPF work with CFI enabled. This allows
     BPF to work with CONFIG_FINEIBT=y

   - Change BPF verifier logic to validate global subprograms lazily
     instead of unconditionally before the main program, so they can be
     guarded using BPF CO-RE techniques

   - Support uid/gid options when mounting bpffs

   - Add a new kfunc which acquires the associated cgroup of a task
     within a specific cgroup v1 hierarchy where the latter is
     identified by its id

   - Extend verifier to allow bpf_refcount_acquire() of a map value
     field obtained via direct load which is a use-case needed in
     sched_ext

   - Add BPF link_info support for uprobe multi link along with bpftool
     integration for the latter

   - Support for VLAN tag in XDP hints

   - Remove deprecated bpfilter kernel leftovers given the project is
     developed in user-space (https://github.com/facebook/bpfilter)

  Misc:

   - Support for parellel TC self-tests execution

   - Increase MPTCP self-tests coverage

   - Updated the bridge documentation, including several so-far
     undocumented features

   - Convert all the net self-tests to run in unique netns, to avoid
     random failures due to conflict and allow concurrent runs

   - Add TCP-AO self-tests

   - Add kunit tests for both cfg80211 and mac80211

   - Autogenerate Netlink families documentation from YAML spec

   - Add yml-gen support for fixed headers and recursive nests, the tool
     can now generate user-space code for all genetlink families for
     which we have specs

   - A bunch of additional module descriptions fixes

   - Catch incorrect freeing of pages belonging to a page pool

  Driver API:

   - Rust abstractions for network PHY drivers; do not cover yet the
     full C API, but already allow implementing functional PHY drivers
     in rust

   - Introduce queue and NAPI support in the netdev Netlink interface,
     allowing complete access to the device <> NAPIs <> queues
     relationship

   - Introduce notifications filtering for devlink to allow control
     application scale to thousands of instances

   - Improve PHY validation, requesting rate matching information for
     each ethtool link mode supported by both the PHY and host

   - Add support for ethtool symmetric-xor RSS hash

   - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
     platform

   - Expose pin fractional frequency offset value over new DPLL generic
     netlink attribute

   - Convert older drivers to platform remove callback returning void
