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.
