Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.

- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.

- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.

- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.

- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.

- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.

- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.

Netfilter:

- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.

- Implement support for wildcard netdevice in netdev basechain and
flowtables.

- Integrate conntrack information into nft trace infrastructure.

- Export set count and backend name to userspace, for better
introspection.

BPF:

- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.

- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.

Protocols:

- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.

- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.

- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.

- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.

- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.

- Extend TCP drop-reason support to cover PAWS checks.

Driver API:

- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.

- Converted several device drivers to timestamping APIs.

- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.

Tests and tooling:

- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.

- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.

- Extend MPTCP selftests to improve the code-coverage.

- Add tests for XDP tail adjustment in AF_XDP.

New hardware / drivers:

- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.

- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.

- Broadcom asp-v3.0 ethernet driver.

Merge branch 'refactoring-designware-vlan-code'

Boon Khai Ng says:

====================
Refactoring designware VLAN code.

Refactoring designware VLAN code and introducing support for
hardware-accelerated VLAN stripping for dwxgmac2 IP,
the current patch set consists of two key changes:

1) Refactoring VLAN Functions:
The first change involves moving common VLAN-related functions
of the DesignWare Ethernet MAC into a dedicated file, stmmac_vlan.c.
This refactoring aims to improve code organization and maintainability
by centralizing VLAN handling logic.

2) Renaming all the functions, symbols and macro into more
generic name and consolidate the same function pointer into one.

3) Enabling VLAN for 10G Ethernet MAC IP:
The second change enables VLAN support specifically
for the 10G Ethernet MAC IP. This enhancement leverages
the hardware capabilities of the to perform VLAN stripping,

Changes from previous submmited patches.
v5:
a) Divided the refactor patch in to two patches,
first patch is to move the code into the separate file
and second patch to update the symbol name

b) get the dwmac4 vlan function up to date and port to
stmmac_vlan.c

c) remove the inline function in function pointer and
use only static function defeination.

d) Remove the outer parenthese that is not needed
on the 1 line return statement.

v4:
a) Updated the commit message to explain the descriptors
behaviour on different hardware.

b) Updated the perfect_match variable with the correct
byte order.

net: stmmac: dwxgmac2: Add support for HW-accelerated VLAN stripping

This patch adds support for MAC level VLAN tag stripping for the
dwxgmac2 IP. This feature can be configured through ethtool.
If the rx-vlan-offload is off, then the VLAN tag will be stripped
by the driver. If the rx-vlan-offload is on then the VLAN tag
will be stripped by the MAC.

net: stmmac: stmmac_vlan: rename VLAN functions and symbol to generic symbol.

With the VLAN handling code decoupled from dwmac4 and dwxgmac2 and
consolidated in stmmac_vlan.c, functions and symbols are renamed to
use a generic prefix. This change improves code clarity and
maintainability by reflecting the shared nature of the VLAN logic,
facilitating future enhancements or reuse without being tied to
specific MAC implementations.

No functional changes are introduced in this patch.

Note: The dwxgmac2_update_vlan_hash function is not combined due
to minor differences in setting the VTFE bit. A separate fix patch
will be submitted to align its behavior with the dwmac4 driver.

net: stmmac: Refactor VLAN implementation

Refactor VLAN implementation by moving common code for DWMAC4 and
DWXGMAC IPs into a separate VLAN module. VLAN implementation for
DWMAC4 and DWXGMAC differs only for CSR base address, the descriptor
for the VLAN ID and VLAN VALID bit field.

The descriptor format for VLAN is not moved to the common code due
to hardware-specific differences between DWMAC4 and DWXGMAC.

For the DWMAC4 IP, the Receive Normal Descriptor 0 (RDES0) is
formatted as follows:
31 0
------------------------ -----------------------
RDES0| Inner VLAN TAG [31:16] | Outer VLAN TAG [15:0] |
------------------------ -----------------------

For the DWXGMAC IP, the RDES0 format varies based on the
Tunneled Frame bit (TNP):

a) For Non-Tunneled Frame (TNP=0)

31 0
------------------------ -----------------------
RDES0| Inner VLAN TAG [31:16] | Outer VLAN TAG [15:0] |
------------------------ -----------------------

b) For Tunneled Frame (TNP=1)

31 8 7 3 2 0
--------------------- ------------------ -------
RDES0| VNID/VSID | Reserved | OL2L3 |
--------------------- ------------------ ------

The logic for handling tunneled frames is not yet implemented
in the dwxgmac2_wrback_get_rx_vlan_tci() function. Therefore,
it is prudent to maintain separate functions within their
respective descriptor driver files
(dwxgmac2_descs.c and dwmac4_descs.c).
