net: libwx: Fix the size in RSS hash key population
While trying to fill a random RSS key, the size of the pointer
is being used rather than the actual size of the RSS key.
Fix by passing an appropriate value of the RSS key.
This issue was reported by static coverity analyser.

Networking changes for 6.17.
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 DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.

A treewide cleanup of struct cycle_counter const annotations:
The initial idea of making them const was correct as they were seperate instances. When they got embedded into larger data structures, which are even modified by the callback this got moot. The only reason why this went unnoticed is that the required container_of() casts the const attribute forcefully away. Stop pretending that it is const. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmiGkt0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYodb/D/47tAOcL6qyTxh+E5fDj4h5M2aVQYp+ oLiBY7ejroObCAiMo6v/ajaGNEXvLXEtratFBQv1o7n12rxsKnv/XNdIbAzvMwKm 3vNx9anQ0THFnWiUKCAf/mZBc/Z9uXnjBXY0TeaFLuj4DuUMqGGs/ga32UIvEwW+ VXS592NIHYoK87VA/AIOK8AGX9VesYoxUqZmfmYn5NuJwsJDSgGaQpoH2fBVhU6p B7NRnVLYtFYpeAvL0ihFuOP03HZes5hM2wmqNtoCJJF9e39Eg9DXhsaUw8AIa1fu UCxm5sfNpMR+QN2AizbI5deHZJbFwYPy/cFrZ0AiwCfZt6NATjO7bQjvu/23yPFn klby8GizV0Q7qmiLi45EdPdid5oiBm/lNy6ICP9fN/XlHZFxAsqE/OGx626P+LPs xQK1MpHNjbkCK//X49hxQX6a0BCqSEAG4GOuEEqRxTeD9SZVzIQbcQ6CKOuBqPqc hc5o5N3suzdmq5sujQD0IiL9R960WfzsSgbmdQm+njhRz+LjAx6T419MlyePiu/5 hf8pZjl/SHn1O6RpPfJ501U+tbo1auEnUjXMGcg12dx7KE4w9s7fboFQLXruuVRr UNeVXeMRxZqXSAB1HyKQMI8lZ7nHF6FZUA+xLMusCwIYi7YU0h7I3BxDzxpZV62l zJgslDp7ZqSopw== =C0ua -----END PGP SIGNATURE----- Merge tag 'timers-cleanups-2025-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer cleanups from Thomas Gleixner: "A treewide cleanup of struct cycle_counter const annotations.

net: libwx: properly reset Rx ring descriptor
When device reset is triggered by feature changes such as toggling Rx
VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The
hardware descriptor ring may retain stale values from previous sessions.
And only set the length to 0 in rx_desc[0] would result in building
malformed SKBs. Fix it to ensure a clean slate after device reset.

net: libwx: fix the using of Rx buffer DMA
The wx_rx_buffer structure contained two DMA address fields: 'dma' and
'page_dma'. However, only 'page_dma' was actually initialized and used
to program the Rx descriptor. But 'dma' was uninitialized and used in
some paths.
This could lead to undefined behavior, including DMA errors or
use-after-free, if the uninitialized 'dma' was used. Althrough such
error has not yet occurred, it is worth fixing in the code.

net: ngbe: specify IRQ vector when the number of VFs is 7
For NGBE devices, the queue number is limited to be 1 when SRIOV is
enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is
used for queue, based on the previous patches. But for the hardware
design, the IRQ vector[1] must be allocated for use by the VF[6] when
the number of VFs is 7. So the IRQ vector[0] should be shared for PF
MISC and QUEUE interrupts.
+-----------+----------------------+
| Vector | Assigned To |
+-----------+----------------------+
| Vector 0 | PF MISC and QUEUE |
| Vector 1 | VF 6 |
| Vector 2 | VF 5 |
| Vector 3 | VF 4 |
| Vector 4 | VF 3 |
| Vector 5 | VF 2 |
| Vector 6 | VF 1 |
| Vector 7 | VF 0 |
+-----------+----------------------+
Minimize code modifications, only adjust the IRQ vector number for this
case.

net: wangxun: revert the adjustment of the IRQ vector sequence
Due to hardware limitations of NGBE, queue IRQs can only be requested
on vector 0 to 7. When the number of queues is set to the maximum 8,
the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by
MISC interrupt, and althrough the vector 8 is used by queue interrupt,
it is unable to receive packets. This will cause some packets to be
dropped when RSS is enabled and they are assigned to queue 8.
So revert the adjustment of the MISC IRQ location, to make it be the
last one in IRQ vectors.

net: libwx: fix the incorrect display of the queue number
When setting "ethtool -L eth0 combined 1", the number of RX/TX queue is
changed to be 1. RSS is disabled at this moment, and the indices of FDIR
have not be changed in wx_set_rss_queues(). So the combined count still
shows the previous value. This issue was introduced when supporting
FDIR. Fix it for those devices that support FDIR.

time/timecounter: Fix the lie that struct cyclecounter is const
In both the read callback for struct cyclecounter, and in struct timecounter, struct cyclecounter is declared as a const pointer. Unfortunatly, a number of users of this pointer treat it as a non-const pointer as it is burried in a larger structure that is heavily modified by the callback function when accessed. This lie had been hidden by the fact that container_of() "casts away" a const attribute of a pointer without any compiler warning happening at all. Fix this all up by removing the const attribute in the needed places so that everyone can see that the structure really isn't const, but can, and is, modified by the users of it.

Networking changes for 6.16.
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.
- AMD Renoir ethernet device.
- ReakTek MT9888 2.5G ethernet PHY driver.
- Aeonsemi 10G C45 PHYs driver.

net: txgbe: Implement PHYLINK for AML 25G/10G devices
There is a new PHY attached to AML 25G/10G NIC, which is different from SP 10G/1G NIC. But the PHY configuration is handed over to firmware, and also I2C is controlled by firmware. So the different PHYLINK fixed-link mode is added for these devices.

net: txgbe: Distinguish between 40G and 25G devices
For the following patches to support PHYLINK for AML 25G devices, separate MAC type wx_mac_aml40 to maintain the driver of 40G devices. Because 40G devices will complete support later, not now. And this patch makes the 25G devices use some PHYLINK interfaces, but it is not yet create PHYLINK and cannot be used on its own. It is just preparation for the next patches.

net: wangxun: Use specific flag bit to simplify the code
Most of the different code that requires MAC type in the common library is due to NGBE only supports a few queues and pools, unlike TXGBE, which supports 128 queues and 64 pools. This difference accounts for most of the hardware configuration differences in the driver code. So add a flag bit "WX_FLAG_MULTI_64_FUNC" for them to clean-up the driver code.

net: Switch to irq_domain_create_*()
irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

net: libwx: Fix FW mailbox unknown command
For the new SW-FW interaction, missing the error return if there is an
unknown command. It causes the driver to mistakenly believe that the
interaction is complete. This problem occurs when new driver is paired
with old firmware, which does not support the new mailbox commands.

For the new SW-FW interaction, the timeout waiting for the firmware to

Use the 'timeout' parameter instead of fixed timeout value for flexible

Otherwise, the driver will fail to probe because the invalid EEPROM
