Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core & protocols:

- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.

This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.

- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.

- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.

- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.

- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.

- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.

- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.

- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.

- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.

- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

- Reduce tcp socket size by one cache line.

- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.

- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.

- Improve xsk generic performances with cache-alignment-oriented
optimizations.

- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.

Driver API:

- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.

- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.

- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.

- Add helper to create, prepare and enable managed clocks.

Device drivers:

- Add Huawei hinic3 PF etherner driver.

- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.

- Add ethernet driver for MaxLinear MxL862xx switches

- Remove parallel-port Ethernet driver.

- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:

- Generic SDCA support for reporting jack events.
- Continuing platform support, cleanup and feature improements for the
AMD, Intel, Qualcomm and SOF code.
- Platform description improvements for the Cirrus drivers.
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B.

We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.

Merge series from Chin-Ting Kuo <chin-ting_kuo@aspeedtech.com>:

This patch series improves handling of SPI controllers that are

The primary goal of this series is to support non-spi-mem devices in
the ASPEED FMC/SPI controller driver. It also addresses an issue in
the spi-mem framework observed when different types of SPI devices
operate concurrently on the same controller, ensuring that spi-mem
operations are properly serialized.

Merge branch 'geneve-introduce-double-tunnel-gso-gro-support'

Paolo Abeni says:

====================
geneve: introduce double tunnel GSO/GRO support

This is the [belated] incarnation of topic discussed in the last Neconf
[1].

In container orchestration in virtual environments there is a consistent
usage of double UDP tunneling - specifically geneve. Such setup lack
support of GRO and GSO for inter VM traffic.

After commit b430f6c38da6 ("Merge branch 'virtio_udp_tunnel_08_07_2025'
of https://github.com/pabeni/linux-devel") and the qemu cunter-part, VMs
are able to send/receive GSO over UDP aggregated packets.

This series introduces the missing bit for full end-to-end aggregation
in the above mentioned scenario. Specifically:

- introduces a new netdev feature set to generalize existing per device
driver GSO admission check.1
- adds GSO partial support for the geneve and vxlan drivers
- introduces and use a geneve option to assist double tunnel GRO
- adds some simple functional tests for the above.

The new device features set is not strictly needed for the following
work, but avoids the introduction of trivial `ndo_features_check` to
support GSO partial and thus possible performance regression due to the
additional indirect call. Such feature set could be leveraged by a
number of existing drivers (intel, meta and possibly wangxun) to avoid
duplicate code/tests. Such part has been omitted here to keep the series
small.

Both GSO partial support and double GRO support have some downsides.
With the first in place, GSO partial packets will traverse the network
stack 'downstream' the outer geneve UDP tunnel and will be visible by
the udp/IP/IPv6 and by netfilter. Currently only H/W NICs implement GSO
partial support and such packets are visible only via software taps.

Double UDP tunnel GRO will cook 'GSO partial' like aggregate packets,
i.e. the inner UDP encapsulation headers set will still carry the
wire-level lengths and csum, so that segmentation considering such
headers parts of a giant, constant encapsulation header will yield the
correct result.

The correct GSO packet layout is applied when the packet traverse the
outermost geneve encapsulation.

Both GSO partial and double UDP encap are disabled by default and must
be explicitly enabled via, respectively ethtool and geneve device
configuration.

Finally note that the GSO partial feature could potentially be applied
to all the other UDP tunnels, but this series limits its usage to geneve
and vxlan devices.

Explicitly enable GSO and/or GRO and check the skb layout consistency with

The trickest part is account in a robust way the aggregated/unaggregated
