Pull networking updates from Paolo Abeni:
"This is slightly smaller than usual, with the most interesting work
being still around RTNL scope reduction.

Core:

- More core refactoring to reduce the RTNL lock contention, including
preparatory work for the per-network namespace RTNL lock, replacing
RTNL lock with a per device-one to protect NAPI-related net device
data and moving synchronize_net() calls outside such lock.

- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
and more specific TCP coverage.

- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.

- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.

Netfilter:

- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.

- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.

- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.

Protocols:

- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core

- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.

- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.

- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.

- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.

- Support updating keys (re-keying) for connections using kernel TLS
(for TLS 1.3 only).

- Support ipv4-mapped ipv6 address clients in smc-r v2.

- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.

- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.

Driver API:

- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.

- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.

- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.

- Consolidate DSA drivers Energy Efficiency Ethernet support.

- Add EEE management to phylink, making use of the phylib
implementation.

- Add phylib support for in-band capabilities negotiation.

- Simplify how phylib-enabled mac drivers expose the supported
interfaces.

Tests and tooling:

- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.

- Increase TCP selftest coverage importing several packetdrill
test-cases.

- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

- Add YNL support for decoding the link types used in net self-tests,
allowing a single build to run both net and drivers/net.

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.
