#     Merge tag 'net-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     Pull networking updates from Jakub Kicinski:
#      "Core & protocols:
#     
#        - Complete rework of garbage collection of AF_UNIX sockets.
#     
#          AF_UNIX is prone to forming reference count cycles due to fd
#          passing functionality. New method based on Tarjan's Strongly
#          Connected Components algorithm should be both faster and remove a
#          lot of workarounds we accumulated over the years.
#     
#        - Add TCP fraglist GRO support, allowing chaining multiple TCP
#          packets and forwarding them together. Useful for small switches /
#          routers which lack basic checksum offload in some scenarios (e.g.
#          PPPoE).
#     
#        - Support using SMP threads for handling packet backlog i.e. packet
#          processing from software interfaces and old drivers which don't use
#          NAPI. This helps move the processing out of the softirq jumble.
#     
#        - Continue work of converting from rtnl lock to RCU protection.
#     
#          Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
#          address labels, netdev threaded NAPI sysfs files, bonding driver's
#          sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
#          TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
#          of the link information available via rtnetlink.
#     
#        - Small optimizations from Eric to UDP wake up handling, memory
#          accounting, RPS/RFS implementation, TCP packet sizing etc.
#     
#        - Allow direct page recycling in the bulk API used by XDP, for +2%
#          PPS.
#     
#        - Support peek with an offset on TCP sockets.
#     
#        - Add MPTCP APIs for querying last time packets were received/sent/acked
#          and whether MPTCP "upgrade" succeeded on a TCP socket.
#     
#        - Add intra-node communication shortcut to improve SMC performance.
#     
#        - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
#          driver.
#     
#        - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
#     
#        - Add reset reasons for tracing what caused a TCP reset to be sent.
#     
#        - Introduce direction attribute for xfrm (IPSec) states. State can be
#          used either for input or output packet processing.
#     
#       Things we sprinkled into general kernel code:
#     
#        - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
#     
#          This required touch-ups and renaming of a few existing users.
#     
#        - Add Endian-dependent __counted_by_{le,be} annotations.
#     
#        - Make building selftests "quieter" by printing summaries like
#          "CC object.o" rather than full commands with all the arguments.
#     
#       Netfilter:
#     
#        - Use GFP_KERNEL to clone elements, to deal better with OOM
#          situations and avoid failures in the .commit step.
#     
#       BPF:
#     
#        - Add eBPF JIT for ARCv2 CPUs.
#     
#        - Support attaching kprobe BPF programs through kprobe_multi link in
#          a session mode, meaning, a BPF program is attached to both function
#          entry and return, the entry program can decide if the return
#          program gets executed and the entry program can share u64 cookie
#          value with return program. "Session mode" is a common use-case for
#          tetragon and bpftrace.
#     
#        - Add the ability to specify and retrieve BPF cookie for raw
#          tracepoint programs in order to ease migration from classic to raw
#          tracepoints.
#     
#        - Add an internal-only BPF per-CPU instruction for resolving per-CPU
#          memory addresses and implement support in x86, ARM64 and RISC-V
#          JITs. This allows inlining functions which need to access per-CPU
#          state.
#     
#        - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
#          atomics in bpf_arena which can be JITed as a single x86
#          instruction. Support BPF arena on ARM64.
#     
#        - Add a new bpf_wq API for deferring events and refactor
#          process-context bpf_timer code to keep common code where possible.
#     
#        - Harden the BPF verifier's and/or/xor value tracking.
#     
#        - Introduce crypto kfuncs to let BPF programs call kernel crypto
#          APIs.
#     
#        - Support bpf_tail_call_static() helper for BPF programs with GCC 13.
#     
#        - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
#          program to have code sections where preemption is disabled.
#     
#       Driver API:
#     
#        - Skip software TC processing completely if all installed rules are
#          marked as HW-only, instead of checking the HW-only flag rule by
#          rule.
#     
#        - Add support for configuring PoE (Power over Ethernet), similar to
#          the already existing support for PoDL (Power over Data Line)
#          config.
#     
#        - Initial bits of a queue control API, for now allowing a single
#          queue to be reset without disturbing packet flow to other queues.
#     
#        - Common (ethtool) statistics for hardware timestamping.
#     
#       Tests and tooling:
#     
#        - Remove the need to create a config file to run the net forwarding
#          tests so that a naive "make run_tests" can exercise them.
#     
#        - Define a method of writing tests which require an external endpoint
#          to communicate with (to send/receive data towards the test
#          machine). Add a few such tests.
#     
#        - Create a shared code library for writing Python tests. Expose the
#          YAML Netlink library from tools/ to the tests for easy Netlink
#          access.
#     
#        - Move netfilter tests under net/, extend them, separate performance
#          tests from correctness tests, and iron out issues found by running
#          them "on every commit".
#     
#        - Refactor BPF selftests to use common network helpers.
#     
#        - Further work filling in YAML definitions of Netlink messages for:
#          nftables, team driver, bonding interfaces, vlan interfaces, VF
#          info, TC u32 mark, TC police action.
#     
#        - Teach Python YAML Netlink to decode attribute policies.
#     
#        - Extend the definition of the "indexed array" construct in the specs
#          to cover arrays of scalars rather than just nests.
#     
#        - Add hyperlinks between definitions in generated Netlink docs.
#     
#       Drivers:
#     
#        - Make sure unsupported flower control flags are rejected by drivers,
#          and make more drivers report errors directly to the application
#          rather than dmesg (large number of driver changes from Asbjørn
#          Sloth Tønnesen).
