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.
