#     Merge tag 'net-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     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.
#
