Pull networking updates from Paolo Abeni:
 "This includes a significant number of low-priority fixes - especially
  in the NIC drivers area - that we deferred from the last few RCs in
  the previous cycle, which can't be easily outlined in the synopsis
  below.

  Core & protocols:

   - Continue the work on removing rtnl_lock dependencies:
      - per-netns ARP and ND neighbour tables, with the default settings
        now configurable per netns (inheritance from init_net is
        controlled by the new net.core.neigh_inherit_init_net sysctl)
      - RCU-protected configuration and rtnl_lock-less fill_info() for
        hsr, netkit, sit, vlan and vxlan devices
      - per-netns device unregistration for ip tunnel and gre devices
      - use the netdev instance lock instead of rtnl_lock when reading
        speed and duplex via sysfs
      - batch the flushing of uncached routes at device unregistration
        time, relieving rtnl_lock contention on netns dismantle.

   - Add hardware pacing offload support, admin-controlled via a new
     rtnetlink attribute, with sch_fq integration (implemented in idpf).

   - Re-segment BIG TCP GSO packets into GSO packets fitting the egress
     device limits instead of plain MSS-sized segments, improving
     throughput for mixed BIG TCP / non-BIG TCP paths by up to 70%.

   - Generate RSS keys that spread flows over all the RX queues; the
     previous random keys could leave some queues unused.

   - Optimize the bridge VLAN forwarding paths: cache the port-VLAN in
     fdb entries and consider only VLAN members when flooding, for ~10%
     more Mpps in the fdb forwarding path.

   - A few TCP/IP performance improvements aimed at efficient cache
     usage and reducing contention.

   - Add the TCP ROCCET congestion control, a CUBIC variant aimed at
     avoiding bufferbloat in cellular networks.

   - Continue the conversion of getsockopt callbacks to sockopt_t.

   - Add an ethtool command to list the front-facing ports of an
     interface, including SFP cages and modules, using the phy_port
     representation.

   - Enable BIG TCP support for bareudp tunnels.

   - Remove the IPV6_ADDRFORM socket option and disallow buggy TCP state
     transitions (listen() + shutdown() + connect() and connect() +
     connect(AF_UNSPEC) + listen()).

   - Remove most BUG_ON()s from core packet processing, replacing them
     with error paths.

  Wireless:

   - Latency improvements, including lockless station get/dump and
     beacon updates, plus RTNL reduction and locking cleanups.

   - Infrastructure for non-station TX/RX with MLO.

   - NAN (Wi-Fi Aware) Instant Communication support and other NAN
     improvements.

   - Control frame Integrity Protocol (CIP) and protected TWT support.

   - Improvements for AP regulatory checks.

  Netfilter:

   - Disable br_netfilter in user namespaces and schedule it for removal
     in 2027.

   - Restrict the raw table in nft_compat to the specific family, hook
     and priority.

   - Prepare the flowtable for mixed IPv4-over-IPv6 tunneling (and vice
     versa).

   - Use GFP_KERNEL_ACCOUNT for most netfilter allocations, for better
     integration with memcg.

   - Allow discovering conntrack zone filtering support in ctnetlink
     dumps, and fix nfnetlink_hook handling of large dumps.

  Deletions:

   - Move the LLC type 2 sockets out of tree. There are no known users
     and the code attracts a never-ending stream of LLM-driven fixes.

  Device drivers:

   - New drivers:
      - Meta Platforms NIC (mpnic), the second-generation NIC from Meta
