#     Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     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
#
