Merge tag 'net-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Wrap datapath globals into net_aligned_data, to avoid false sharing

- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)

- Add SO_INQ and SCM_INQ support to AF_UNIX

- Add SIOCINQ support to AF_VSOCK

- Add TCP_MAXSEG sockopt to MPTCP

- Add IPv6 force_forwarding sysctl to enable forwarding per interface

- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB

- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users

- Convert TCP send queue handling from tasklet to BH workque

- Improve BPF iteration over TCP sockets to see each socket exactly
once

- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code

- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization

- Allow multicast routing to take effect on locally-generated packets

- Add output interface argument for End.X in segment routing

- MCTP: add support for gateway routing, improve bind() handling

- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink

- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed

- Support NUD_PERMANENT for proxy neighbor entries

- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM

- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests

- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup

- Support inspecting ref_tracker state via DebugFS

- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links

- Allow providing upcall pid for the 'execute' command in openvswitch

- Remove DCCP support from Netfilter's conntrack

- Disallow multiple packet duplications in the queuing layer

- Prevent use of deprecated iptables code on PREEMPT_RT

Driver API:

- Support RSS and hashing configuration over ethtool Netlink

- Add dedicated ethtool callbacks for getting and setting hashing
fields

- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc

Support providing clock reference and SYNC over separate DPLL
inputs

- Support traffic classes in devlink rate API for bandwidth
management

Merge branch 'cn20k-silicon-with-mbox-support'

Subbaraya Sundeep says:

====================
CN20K silicon with mbox support

CN20K is the next generation silicon in the Octeon series with various
improvements and new features.

Along with other changes the mailbox communication mechanism between RVU
(Resource virtualization Unit) SRIOV PFs/VFs with Admin function (AF) has
also gone through some changes.

Some of those changes are
- Separate IRQs for mbox request and response/ack.
- Configurable mbox size, default being 64KB.
- Ability for VFs to communicate with RVU AF instead of going through
parent SRIOV PF.

Due to more memory requirement due to configurable mbox size, mbox memory
will now have to be allocated by
- AF (PF0) for communicating with other PFs and all VFs in the system.
- PF for communicating with it's child VFs.

On previous silicons mbox memory was reserved and configured by firmware.

This patch series add basic mbox support for AF (PF0) <=> PFs and
PF <=> VFs. AF <=> VFs communication and variable mbox size support will
come in later.

Patch #1 Supported co-existance of bit encoding PFs and VFs in 16-bit
hardware pcifunc format between CN20K silicon and older octeon
series. Also exported PF,VF masks and shifts present in mailbox
module to all other modules.

Patch #2 Added basic mbox operation APIs and structures to support both
CN20K and previous version of silicons.

Patch #3 This patch adds support for basic mbox infrastructure
implementation for CN20K silicon in AF perspective. There are
few updates w.r.t MBOX ACK interrupt and offsets in CN20k.

Patch #4 Added mbox implementation between NIC PF and AF for CN20K.

Patch #5 Added mbox communication support between AF and AF's VFs.

Patch #6 This patch adds support for MBOX communication between NIC PF and
its VFs.
