#     Merge tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
#     
#     Pull networking updates from Paolo Abeni:
#      "The most significant set of changes is the per netns RTNL. The new
#       behavior is disabled by default, regression risk should be contained.
#     
#       Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
#       default value from PTP_1588_CLOCK_KVM, as the first is intended to be
#       a more reliable replacement for the latter.
#     
#       Core:
#     
#        - Started a very large, in-progress, effort to make the RTNL lock
#          scope per network-namespace, thus reducing the lock contention
#          significantly in the containerized use-case, comprising:
#            - RCU-ified some relevant slices of the FIB control path
#            - introduce basic per netns locking helpers
#            - namespacified the IPv4 address hash table
#            - remove rtnl_register{,_module}() in favour of
#              rtnl_register_many()
#            - refactor rtnl_{new,del,set}link() moving as much validation as
#              possible out of RTNL lock
#            - convert all phonet doit() and dumpit() handlers to RCU
#            - convert IPv4 addresses manipulation to per-netns RTNL
#            - convert virtual interface creation to per-netns RTNL
#          the per-netns lock infrastructure is guarded by the
#          CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
#     
#        - Introduce NAPI suspension, to efficiently switching between busy
#          polling (NAPI processing suspended) and normal processing.
#     
#        - Migrate the IPv4 routing input, output and control path from direct
#          ToS usage to DSCP macros. This is a work in progress to make ECN
#          handling consistent and reliable.
#     
#        - Add drop reasons support to the IPv4 rotue input path, allowing
#          better introspection in case of packets drop.
#     
#        - Make FIB seqnum lockless, dropping RTNL protection for read access.
#     
#        - Make inet{,v6} addresses hashing less predicable.
#     
#        - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
#          and timestamps
#     
#       Things we sprinkled into general kernel code:
#     
#        - Add small file operations for debugfs, to reduce the struct ops
#          size.
#     
#        - Refactoring and optimization for the implementation of page_frag
#          API, This is a preparatory work to consolidate the page_frag
#          implementation.
#     
#       Netfilter:
#     
#        - Optimize set element transactions to reduce memory consumption
#     
#        - Extended netlink error reporting for attribute parser failure.
#     
#        - Make legacy xtables configs user selectable, giving users the
#          option to configure iptables without enabling any other config.
#     
#        - Address a lot of false-positive RCU issues, pointed by recent CI
#          improvements.
#     
#       BPF:
#     
#        - Put xsk sockets on a struct diet and add various cleanups. Overall,
#          this helps to bump performance by 12% for some workloads.
#     
#        - Extend BPF selftests to increase coverage of XDP features in
#          combination with BPF cpumap.
#     
#        - Optimize and homogenize bpf_csum_diff helper for all archs and also
#          add a batch of new BPF selftests for it.
#     
#        - Extend netkit with an option to delegate skb->{mark,priority}
#          scrubbing to its BPF program.
#     
#        - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
#          programs.
#     
#       Protocols:
#     
#        - Introduces 4-tuple hash for connected udp sockets, speeding-up
#          significantly connected sockets lookup.
#     
#        - Add a fastpath for some TCP timers that usually expires after
#          close, the socket lock contention.
#     
#        - Add inbound and outbound xfrm state caches to speed up state
#          lookups.
#     
#        - Avoid sending MPTCP advertisements on stale subflows, reducing
#          risks on loosing them.
#     
#        - Make neighbours table flushing more scalable, maintaining per
#          device neigh lists.
#     
#       Driver API:
#     
#        - Introduce a unified interface to configure transmission H/W
#          shaping, and expose it to user-space via generic-netlink.
#     
#        - Add support for per-NAPI config via netlink. This makes napi
#          configuration persistent across queues removal and re-creation.
#          Requires driver updates, currently supported drivers are:
#          nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
#     
#        - Add ethtool support for writing SFP / PHY firmware blocks.
#     
#        - Track RSS context allocation from ethtool core.
#     
#        - Implement support for mirroring to DSA CPU port, via TC mirror
#          offload.
#     
#        - Consolidate FDB updates notification, to avoid duplicates on
#          device-specific entries.
#     
#        - Expose DPLL clock quality level to the user-space.
#     
#        - Support master-slave PHY config via device tree.
#     
#       Tests and tooling:
#     
#        - forwarding: introduce deferred commands, to simplify the cleanup
#          phase
#     
#       Drivers:
#     
#        - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
#          Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
#          IRQs and queues to NAPI IDs, allowing busy polling and better
#          introspection.
