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

- X-Powers AC200/AC300 Fast Ethernet PHYs
