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

Merge branch 'move-can-skb-headroom-content-to-skb-extensions'

Oliver Hartkopp says:

====================
move CAN skb headroom content to skb extensions

CAN bus related skbuffs (ETH_P_CAN/ETH_P_CANFD/ETH_P_CANXL) simply contain
CAN frame structs for CAN CC/FD/XL of skb->len length at skb->data. Those
CAN skbs do not have network/mac/transport headers nor other such
references for encapsulated protocols like ethernet/IP protocols.

To store data for CAN specific use-cases all CAN bus related skbuffs are
created with a 16 byte private skb headroom (struct can_skb_priv). Using
the skb headroom and accessing skb->head for this private data led to
several problems in the past likely due to "The struct can_skb_priv
business is highly unconventional for the networking stack." [1]

This patch set aims to remove the unconventional skb headroom usage for CAN
bus related skbuffs and use the common skb extensions instead.

can: add CAN skb extension infrastructure

To remove the private CAN bus skb headroom infrastructure 8 bytes need to
be stored in the skb. The skb extensions are a common pattern and an easy
and efficient way to hold private data travelling along with the skb. We
only need the skb_ext_add() and skb_ext_find() functions to allocate and
access CAN specific content as the skb helpers to copy/clone/free skbs
automatically take care of skb extensions and their final removal.

This patch introduces the complete CAN skb extensions infrastructure:
- add struct can_skb_ext in new file include/net/can.h
- add include/net/can.h in MAINTAINERS
- add SKB_EXT_CAN to skbuff.c and skbuff.h
- select SKB_EXTENSIONS in Kconfig when CONFIG_CAN is enabled
- check for existing CAN skb extensions in can_rcv() in af_can.c
- add CAN skb extensions allocation at every skb_alloc() location
- duplicate the skb extensions if cloning outgoing skbs (framelen/gw_hops)
- introduce can_skb_ext_add() and can_skb_ext_find() helpers

The patch also corrects an indention issue in the original code from 2018:

Among the few spi-mem patches, they are needed for building the SPI NAND
changes (especially the ODTR introduction at the end) and therefore an

Merge series from André Draszik <andre.draszik@linaro.org>:

With these attached patches it becomes possible again to support
hardware designs with multiple PMICs where individual rails of each act
as required supplies for rails of the other (due to the latter being
e.g. always-on), and vice-versa.

Google Pixel 6 and 6 Pro (oriole and raven) are examples of such
designs.

Rather than returning -EPORBE_DEFER in regulator_register() when
set_machine_constraints() fails with -EPROBE_DEFER (due to missing
required supplies), we still allow rail registration and try to
reresolve supplies each time a new rail gets registered.

This is implemented using a bus (regulator bus), which allows the core
to reresolve supplies for regulators that still need them whenever new
regulators (i.e. devices) are added.

Using a bus also solves existing problems around late resolution of
supplies as mentioned in the commit message introducing that bus.

The series starts with a few bug fixes and the last two commits
implement the changes mentioned above, but do depend on the bug fixes.

Support effective VF bandwidth query in LAG mode

Currently, mlx5 driver exposes only the parent function's speed to VFs,
providing no way to query the actual effective bandwidth in LAG and
MPESW configurations. This limitation prevents userspace and
upper-layer software from obtaining accurate bandwidth information,
which impacts traffic scheduling decisions.

This series addresses this by:

1. Adding mlx5 internal logic to calculate and propagate the effective
aggregated LAG speed to all attached vports. The vport speeds are
dynamically updated when LAG member link states change.

2. Extending RDMA core with a new ib_query_port_speed() verb and an
IB_EVENT_DEVICE_SPEED_CHANGE async event. These interfaces expose
the effective port speed to userspace, supporting speeds that are
not expressible as IB speed * width (where width is 2^n).

This series enables userspace applications to query the effective
port speed and receive notifications on speed changes in real-time.
In LAG configurations, each mlx5 port reports the aggregated bandwidth
of all active LAG members.
