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.

Merge branch 'net-dsa-initial-support-for-maxlinear-mxl862xx-switches'
Daniel Golle says:
==================== net: dsa: initial support for MaxLinear MxL862xx switches
This series adds very basic DSA support for the MaxLinear MxL86252 (5x 2500Base-T PHYs) and MxL86282 (8x 2500Base-T PHYs) switches. In addition to the 2.5G TP ports both switches also come with two SerDes interfaces which can be used either to connect external PHYs or SFP cages, or as CPU port when using the switch with this DSA driver.
MxL862xx integrates a firmware running on an embedded processor (based on Zephyr RTOS). Host interaction uses a simple netlink-like API transported over MDIO/MMD.
This series includes only what's needed to pass traffic between user ports and the CPU port: relayed MDIO to internal PHYs, basic port enable/disable, and CPU-port special tagging.
The SerDes interface of the CPU port is automatically configured by the switch after reset using a board-specific configuration stored together with the firmware in the flash chip attached to the switch, so no action is needed from the driver to setup the interface mode of the CPU port.
Also MAC settings of the PHY ports are automatically configured, which means the driver works fine with phylink_mac_ops being all no-op stubs.
Multiple follow up series will bring support for setting up the other SerDes PCS interface (ie. not used for the CPU port), bridge, VLAN, ... offloading, and support for using an 802.1Q-based special tag instead of the proprietary 8-byte tag. ====================

net: dsa: add basic initial driver for MxL862xx switches
Add very basic DSA driver for MaxLinear's MxL862xx switches.
In contrast to previous MaxLinear switches the MxL862xx has a built-in processor that runs a sophisticated firmware based on Zephyr RTOS. Interaction between the host and the switch hence is organized using a software API of that firmware rather than accessing hardware registers directly.
Add descriptions of the most basic firmware API calls to access the built-in MDIO bus hosting the 2.5GE PHYs, basic port control as well as setting up the CPU port.
Implement a very basic DSA driver using that API which is sufficient to get packets flowing between the user ports and the CPU port.
The firmware offers all features one would expect from a modern switch hardware, they are going to be added one by one in follow-up patch series.
