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.

Merge branch 'stp-rstp-switch-support-for-pru-icssm-ethernet-driver'

Parvathi Pudi says:

====================
STP/RSTP SWITCH support for PRU-ICSSM Ethernet driver

The DUAL-EMAC patch series for Megabit Industrial Communication Sub-system
(ICSSM), which provides the foundational support for Ethernet functionality
over PRU-ICSS on the TI SOCs (AM335x, AM437x, and AM57x), was merged into
net-next recently [1].

This patch series enhances the PRU-ICSSM Ethernet driver to support bridge
(STP/RSTP) SWITCH mode, which has been implemented using the "switchdev"
framework and interacts with the "mstp daemon" for STP and RSTP management
in userspace.

When the SWITCH mode is enabled, forwarding of Ethernet packets using
either the traditional store-and-forward mechanism or via cut-through is
offloaded to the two PRU based Ethernet interfaces available within the
ICSSM. The firmware running on the PRU inspects the bridge port states and
performs necessary checks before forwarding a packet. This improves the
overall system performance and significantly reduces the packet forwarding
latency.

Protocol switching from Dual-EMAC to bridge (STP/RSTP) SWITCH mode can be
done as follows.

Assuming eth2 and eth3 are the two physical ports of the ICSS2 instance:

>> brctl addbr br0
>> ip maddr add 01:80:c2:00:00:00 dev br0
>> ip link set dev br0 address $(cat /sys/class/net/eth2/address)
>> brctl addif br0 eth2
>> brctl addif br0 eth3
>> mstpd
>> brctl stp br0 on
>> mstpctl setforcevers br0 rstp
>> ip link set dev br0 up

To revert back to the default dual EMAC mode, the steps are as follows:

>> ip link set dev br0 down
>> brctl delif br0 eth2
>> brctl delif br0 eth3
>> brctl delbr br0

The patches presented in this series have gone through the patch verification
tools and no warnings or errors are reported.

net: ti: icssm-prueth: Add helper functions to configure and maintain FDB

Introduce helper functions to configure and maintain Forwarding
Database (FDB) tables to aid with the switch mode feature for PRU-ICSS
ports. The PRU-ICSS FDB is maintained such that it is always in sync with
the Linux bridge driver FDB.

The FDB is used by the driver to determine whether to flood a packet,
received from the user plane, to both ports or direct it to a specific port
using the flags in the FDB table entry.

The FDB is implemented in two main components: the Index table and the
MAC Address table. Adding, deleting, and maintaining entries are handled
by the PRUETH driver. There are two types of entries:

Dynamic: created from the received packets and are subject to aging.
Static: created by the user and these entries never age out.

8-bit hash value obtained using the source MAC address is used to identify
the index to the Index/Hash table. A bucket-based approach is used to
collate source MAC addresses with the same hash value. The Index/Hash table
holds the bucket index (16-bit value) and the number of entries in the
bucket with the same hash value (16-bit value). This table can hold up to
256 entries, with each entry consuming 4 bytes of memory. The bucket index
value points to the MAC address table indicating the start of MAC addresses
having the same hash values.

Each entry in the MAC Address table consists of:
1. 6 bytes of the MAC address,
2. 2-byte aging time, and
3. 1-byte each for port information and flags respectively.

When a new entry is added to the FDB, the hash value is calculated using an
XOR operation on the 6-byte MAC address. The result is used as an index
into the Hash/Index table to check if any entries exist. If no entries are
present, the first available empty slot in the MAC Address table is
allocated to insert this MAC address. If entries with the same hash value
are already present, the new MAC address entry is added to the MAC Address
table in such a way that it ensures all entries are grouped together and
sorted in ascending MAC address order. This approach helps efficiently
manage FDB entries.

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS

- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions

- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities

- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)

- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath

- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW

- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds

- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete

- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches

- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios

- Improve netfilter matching performance on large sets

- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes

- Allow bridges to redirect to a backup port when the bridge port is
administratively down

- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups

- Add RCU safety to dst->dev, closing a lot of possible races

- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication

- Supports pulling data from an skb frag into the linear area of an
XDP buffer

Things we sprinkled into general kernel code:

- Generate netlink documentation from YAML using an integrated YAML
parser

Driver API:

- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection

- Introduce API for fetching the DMA device for a given queue,
allowing TCP zerocopy RX on more H/W setups

- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath

- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration

- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause

- Support for DPLL phase offset exponential moving average,
controlling the average smoothing factor

Device drivers:

- Add a new Huawei driver for 3rd gen NIC (hinic3)

- Add a new SpacemiT driver for K1 ethernet MAC

- Add a generic abstraction for shared memory communication
devices (dibps)

- Ethernet high-speed NICs:

====================
PRU-ICSSM Ethernet Driver

The Programmable Real-Time Unit Industrial Communication Sub-system (PRU-ICSS)
is available on the TI SOCs in two flavors: Gigabit ICSS (ICSSG) and the older
Megabit ICSS (ICSSM).

Support for ICSSG Dual-EMAC mode has already been mainlined [1] and the
fundamental components/drivers such as PRUSS driver, Remoteproc driver,
PRU-ICSS INTC, and PRU-ICSS IEP drivers are already available in the mainline
Linux kernel. The current set of patch series builds on top of these components
and introduces changes to support the Dual-EMAC using ICSSM on the TI AM57xx,
AM437x and AM335x devices.

AM335x, AM437x and AM57xx devices may have either one or two PRU-ICSS instances
with two 32-bit RISC PRU cores. Each PRU core has (a) dedicated Ethernet interface
(MII, MDIO), timers, capture modules, and serial communication interfaces, and
(b) dedicated data and instruction RAM as well as shared RAM for inter PRU
communication within the PRU-ICSS.

These patches add support for basic RX and TX functionality over PRU Ethernet
ports in Dual-EMAC mode.

Further, note that these are the initial set of patches for a single instance of
PRU-ICSS Ethernet. Additional features such as Ethtool support, VLAN Filtering,
Multicast Filtering, Promiscuous mode, Storm prevention, Interrupt coalescing,
Linux PTP (ptp4l) Ordinary clock and Switch mode support for AM335x, AM437x
and AM57x along with support for a second instance of PRU-ICSS on AM57x
will be posted subsequently.

The patches presented in this series have gone through the patch verification
tools and no warnings or errors are reported. Sample test logs obtained from AM33x,
AM43x and AM57x verifying the functionality on Linux next kernel are available here:
