Pull networking updates from Jakub Kicinski:
 "Core & protocols:

   - Support usec resolution of TCP timestamps, enabled selectively by a
     route attribute.

   - Defer regular TCP ACK while processing socket backlog, try to send
     a cumulative ACK at the end. Increase single TCP flow performance
     on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).

   - The Fair Queuing (FQ) packet scheduler:
       - add built-in 3 band prio / WRR scheduling
       - support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
       - improve inactive flow reporting
       - optimize the layout of structures for better cache locality

   - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
     replacement for the old MD5 option.

   - Add more retransmission timeout (RTO) related statistics to
     TCP_INFO.

   - Support sending fragmented skbs over vsock sockets.

   - Make sure we send SIGPIPE for vsock sockets if socket was
     shutdown().

   - Add sysctl for ignoring lower limit on lifetime in Router
     Advertisement PIO, based on an in-progress IETF draft.

   - Add sysctl to control activation of TCP ping-pong mode.

   - Add sysctl to make connection timeout in MPTCP configurable.

   - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
     limit the number of wakeups.

   - Support netlink GET for MDB (multicast forwarding), allowing user
     space to request a single MDB entry instead of dumping the entire
     table.

   - Support selective FDB flushing in the VXLAN tunnel driver.

   - Allow limiting learned FDB entries in bridges, prevent OOM attacks.

   - Allow controlling via configfs netconsole targets which were
     created via the kernel cmdline at boot, rather than via configfs at
     runtime.

   - Support multiple PTP timestamp event queue readers with different
     filters.

   - MCTP over I3C.

  BPF:

   - Add new veth-like netdevice where BPF program defines the logic of
     the xmit routine. It can operate in L3 and L2 mode.

   - Support exceptions - allow asserting conditions which should never
     be true but are hard for the verifier to infer. With some extra
     flexibility around handling of the exit / failure:

          https://lwn.net/Articles/938435/

   - Add support for local per-cpu kptr, allow allocating and storing
     per-cpu objects in maps. Access to those objects operates on the
     value for the current CPU.

     This allows to deprecate local one-off implementations of per-CPU
     storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.

   - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
     for systemd to re-implement the LogNamespace feature which allows
     running multiple instances of systemd-journald to process the logs
     of different services.

   - Enable open-coded task_vma iteration, after maple tree conversion
     made it hard to directly walk VMAs in tracing programs.

   - Add open-coded task, css_task and css iterator support. One of the
     use cases is customizable OOM victim selection via BPF.

   - Allow source address selection with bpf_*_fib_lookup().

   - Add ability to pin BPF timer to the current CPU.

   - Prevent creation of infinite loops by combining tail calls and
     fentry/fexit programs.

   - Add missed stats for kprobes to retrieve the number of missed
     kprobe executions and subsequent executions of BPF programs.

   - Inherit system settings for CPU security mitigations.

   - Add BPF v4 CPU instruction support for arm32 and s390x.

  Changes to common code:

   - overflow: add DEFINE_FLEX() for on-stack definition of structs with
     flexible array members.

   - Process doc update with more guidance for reviewers.

  Driver API:

   - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
     mutex in most places and remove a lot of smaller locks.

   - Create a common DPLL configuration API. Allow configuring and
     querying state of PLL circuits used for clock syntonization, in
     network time distribution.

   - Unify fragmented and full page allocation APIs in page pool code.
     Let drivers be ignorant of PAGE_SIZE.

   - Rework PHY state machine to avoid races with calls to phy_stop().

   - Notify DSA drivers of MAC address changes on user ports, improve
     correctness of offloads which depend on matching port MAC
     addresses.

   - Allow antenna control on injected WiFi frames.

   - Reduce the number of variants of napi_schedule().

   - Simplify error handling when composing devlink health messages.

  Misc:

   - A lot of KCSAN data race "fixes", from Eric.

   - A lot of __counted_by() annotations, from Kees.

   - A lot of strncpy -> strscpy and printf format fixes.

   - Replace master/slave terminology with conduit/user in DSA drivers.

   - Handful of KUnit tests for netdev and WiFi core.

   - AppleTalk COPS.

   - AppleTalk ipddp.

   - TI AR7 CPMAC Ethernet driver.
