#     Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     Pull networking updates from Jakub Kicinski:
#      "Core & protocols:
#     
#        - Large effort by Eric to lower rtnl_lock pressure and remove locks:
#     
#           - Make commonly used parts of rtnetlink (address, route dumps
#             etc) lockless, protected by RCU instead of rtnl_lock.
#     
#           - Add a netns exit callback which already holds rtnl_lock,
#             allowing netns exit to take rtnl_lock once in the core instead
#             of once for each driver / callback.
#     
#           - Remove locks / serialization in the socket diag interface.
#     
#           - Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
#     
#           - Remove the dev_base_lock, depend on RCU where necessary.
#     
#        - Support busy polling on a per-epoll context basis. Poll length and
#          budget parameters can be set independently of system defaults.
#     
#        - Introduce struct net_hotdata, to make sure read-mostly global
#          config variables fit in as few cache lines as possible.
#     
#        - Add optional per-nexthop statistics to ease monitoring / debug of
#          ECMP imbalance problems.
#     
#        - Support TCP_NOTSENT_LOWAT in MPTCP.
#     
#        - Ensure that IPv6 temporary addresses' preferred lifetimes are long
#          enough, compared to other configured lifetimes, and at least 2 sec.
#     
#        - Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
#     
#        - Add support for the independent control state machine for bonding
#          per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
#          control state machine.
#     
#        - Add "network ID" to MCTP socket APIs to support hosts with multiple
#          disjoint MCTP networks.
#     
#        - Re-use the mono_delivery_time skbuff bit for packets which user
#          space wants to be sent at a specified time. Maintain the timing
#          information while traversing veth links, bridge etc.
#     
#        - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
#     
#        - Simplify many places iterating over netdevs by using an xarray
#          instead of a hash table walk (hash table remains in place, for use
#          on fastpaths).
#     
#        - Speed up scanning for expired routes by keeping a dedicated list.
#     
#        - Speed up "generic" XDP by trying harder to avoid large allocations.
#     
#        - Support attaching arbitrary metadata to netconsole messages.
#     
#       Things we sprinkled into general kernel code:
#     
#        - Enforce VM_IOREMAP flag and range in ioremap_page_range and
#          introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
#          bpf_arena).
#     
#        - Rework selftest harness to enable the use of the full range of ksft
#          exit code (pass, fail, skip, xfail, xpass).
#     
#       Netfilter:
#     
#        - Allow userspace to define a table that is exclusively owned by a
#          daemon (via netlink socket aliveness) without auto-removing this
#          table when the userspace program exits. Such table gets marked as
#          orphaned and a restarting management daemon can re-attach/regain
#          ownership.
#     
#        - Speed up element insertions to nftables' concatenated-ranges set
#          type. Compact a few related data structures.
#     
#       BPF:
#     
#        - Add BPF token support for delegating a subset of BPF subsystem
#          functionality from privileged system-wide daemons such as systemd
#          through special mount options for userns-bound BPF fs to a trusted
#          & unprivileged application.
#     
#        - Introduce bpf_arena which is sparse shared memory region between
#          BPF program and user space where structures inside the arena can
#          have pointers to other areas of the arena, and pointers work
#          seamlessly for both user-space programs and BPF programs.
#     
#        - Introduce may_goto instruction that is a contract between the
#          verifier and the program. The verifier allows the program to loop
#          assuming it's behaving well, but reserves the right to terminate
#          it.
#     
#        - Extend the BPF verifier to enable static subprog calls in spin lock
#          critical sections.
#     
#        - Support registration of struct_ops types from modules which helps
#          projects like fuse-bpf that seeks to implement a new struct_ops
#          type.
#     
#        - Add support for retrieval of cookies for perf/kprobe multi links.
#     
#        - Support arbitrary TCP SYN cookie generation / validation in the TC
#          layer with BPF to allow creating SYN flood handling in BPF
#          firewalls.
#     
#        - Add code generation to inline the bpf_kptr_xchg() helper which
#          improves performance when stashing/popping the allocated BPF
#          objects.
#     
#       Wireless:
#     
#        - Add SPP (signaling and payload protected) AMSDU support.
#     
#        - Support wider bandwidth OFDMA, as required for EHT operation.
#     
#       Driver API:
#     
#        - Major overhaul of the Energy Efficient Ethernet internals to
#          support new link modes (2.5GE, 5GE), share more code between
#          drivers (especially those using phylib), and encourage more
#          uniform behavior. Convert and clean up drivers.
#     
#        - Define an API for querying per netdev queue statistics from
#          drivers.
#     
#        - IPSec: account in global stats for fully offloaded sessions.
#     
#        - Create a concept of Ethernet PHY Packages at the Device Tree level,
#          to allow parameterizing the existing PHY package code.
#     
#        - Enable Rx hashing (RSS) on GTP protocol fields.
#     
#       Misc:
#     
#        - Improvements and refactoring all over networking selftests.
#     
#        - Create uniform module aliases for TC classifiers, actions, and
#          packet schedulers to simplify creating modprobe policies.
#     
#        - Address all missing MODULE_DESCRIPTION() warnings in networking.
#     
#        - Extend the Netlink descriptions in YAML to cover message
#          encapsulation or "Netlink polymorphism", where interpretation of
#          nested attributes depends on link type, classifier type or some
#          other "class type".
#
