Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.

Core & protocols:

- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT

- Use flex array for netdevice priv area, ensure its cache alignment

- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful

- Support scheduling transmission of packets based on CLOCK_TAI

- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets

- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync

- Improve TCP compliance with RFC 9293 for simultaneous connect()

- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it

- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

- Introduce IPPROTO_SMC for selecting SMC when socket is created

- Allow UDP GSO transmit from devices with no checksum offload

- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding

- nf_tables: shrink memory consumption for transaction objects

Things we sprinkled into general kernel code:

- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]

- Add IRQ information in sysfs for auxiliary bus

- Introduce guard definition for local_lock

- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures

BPF:

- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered

- Add new kfuncs for a generic, open-coded bits iterator

- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head

- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules

- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs

- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter

- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs

Driver API:

- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits

- Track additional RSS contexts in the core, make sure configuration
changes don't break them

- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths

- Support updating firmware on SFP modules

Tests and tooling:

- mptcp: use net/lib.sh to manage netns

- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints

- openvswitch: make test self-contained (don't depend on OvS CLI
tools)

Merge branch 'pcs-xpcs-mmap' into main

Merge branch 'pcs-xpcs-mmap' into main

Serge Semin <fancer says:

====================
net: pcs: xpcs: Add memory-mapped device support

The main goal of this series is to extend the DW XPCS device support in
the kernel. Particularly the patchset adds a support of the DW XPCS
device with the MCI/APB3 IO interface registered as a platform device. In
order to have them utilized by the DW XPCS core the fwnode-based DW XPCS
descriptor creation procedure has been introduced. Finally the STMMAC
driver has been altered to support the DW XPCS passed via the 'pcs-handle'
property.

Note the series has been significantly re-developed since v1. So I even
had to change the subject. Anyway I've done my best to take all the noted
into account.

The series traditionally starts with a set of the preparation patches.
First one just moves the generic DW XPCS IDs macros from the internal
header file to the external one where some other IDs also reside. Second
patch splits up the xpcs_create() method to a set of the coherent
sub-functions for the sake of the further easier updates and to have it
looking less complicated. The goal of the next three patches is to extend
the DW XPCS ID management code by defining a new dw_xpcs_info structure
with both PCS and PMA IDs.

The next two patches provide the DW XPCS device DT-bindings and the
respective platform-device driver for the memory-mapped DW XPCS devices.
Besides the later patch makes use of the introduced dw_xpcs_info structure
to pre-define the DW XPCS IDs based on the platform-device compatible
string. Thus if there is no way to auto-identify the XPCS device
capabilities it can be done based on the custom device IDs passed via the
MDIO-device platform data.

Final DW XPCS driver change is about adding a new method of the DW XPCS
descriptor creation. The xpcs_create_fwnode() function has been introduced
with the same semantics as a similar method recently added to the Lynx PCS
driver. It's supposed to be called with the fwnode pointing to the DW XPCS
device node, for which the XPCS descriptor will be created.

The series is terminated with two STMMAC driver patches. The former one
simplifies the DW XPCS descriptor registration procedure by dropping the
MDIO-bus scanning and creating the descriptor for the particular device
address. The later patch alters the STMMAC PCS setup method so one would
support the DW XPCS specified via the "pcs-handle" property.

That's it for now. Thanks for review in advance. Any tests are very
welcome. After this series is merged in, I'll submit another one which
adds the generic 10GBase-R and 10GBase-X interfaces support to the STMMAC
and DW XPCS driver with the proper CSRs re-initialization, PMA
initialization and reference clock selection as it's described in the
Synopsys DW XPCS HW manual.

net: pcs: xpcs: Add Synopsys DW xPCS platform device driver

Synopsys DesignWare XPCS IP-core can be synthesized with the device CSRs
being accessible over the MCI or APB3 interface instead of the MDIO bus
(see the CSR_INTERFACE HDL parameter). Thus all the PCS registers can be
just memory mapped and be a subject of the standard MMIO operations of
course taking into account the peculiarities of the Clause C45 CSRs
mapping. From that perspective the DW XPCS devices would look as just
normal platform devices for the kernel.

On the other hand in order to have the DW XPCS devices handled by the
pcs-xpcs.c driver they need to be registered in the framework of the
MDIO-subsystem. So the suggested change is about providing a DW XPCS
platform device driver registering a virtual MDIO-bus with a single
MDIO-device representing the DW XPCS device.

DW XPCS platform device is supposed to be described by the respective
compatible string "snps,dw-xpcs" (or with the PMA-specific compatible
string), CSRs memory space and optional peripheral bus and reference clock
sources. Depending on the INDIRECT_ACCESS IP-core synthesize parameter the
memory-mapped reg-space can be represented as either directly or
indirectly mapped Clause 45 space. In the former case the particular
address is determined based on the MMD device and the registers offset (5
+ 16 bits all together) within the device reg-space. In the later case
there is only 8 lower address bits are utilized for the registers mapping
(255 CSRs). The upper bits are supposed to be written into the respective
viewport CSR in order to select the respective MMD sub-page.

Note, only the peripheral bus clock source is requested in the platform
device probe procedure. The core and pad clocks handling has been
implemented in the framework of the xpcs_create() method intentionally
since the clocks-related setups are supposed to be performed later, during
the DW XPCS main configuration procedures. (For instance they will be
required for the DW Gen5 10G PMA configuration.)
