Merge tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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.

- Ethernet high-speed NICs:
- nVidia/Mellanox (mlx5):

When using allmodconfig, .config has CONFIG_LEDS_CLASS=m but
autoconf.h has CONFIG_LEDS_CLASS_MODULE (additional suffix _MODULE)
instead of CONFIG_LEDS_CLASS, which condition CONFIG_LEDS_CLASS in
rtw88/led.h can't work properly.

Add RTW88_LEDS to Kconfig, and use it as condition to fix this problem.
