Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.

It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.

Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.

We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.

The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...

Core & protocols:

- A few steps lowering rtnl_lock dependence:
- per-netns netdev unregistration for select SW drivers (e.g.
veth, ipvlan, tunnels)
- rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE)
- prepare software drivers and TC qdiscs for rtnl_lock-less GET

- Report the per-group user count via RTM_GETMULTICAST

useful handling of LSM denials when receiving SCM_RIGHTS messages:
instead of truncating the message at the first blocked fd, keep
every fd slot and store the LSM errno in the blocked slot

Merge branch 'add-dapu-telecom-dap8211r-i-gigabit-ethernet-phy-driver'

Artem Shimko says:

====================
Add DAPU Telecom DAP8211R(I) Gigabit Ethernet PHY driver

This series adds support for the DAPU Telecom DAP8211R(I) Gigabit
Ethernet PHY, commonly used in enterprise and industrial networking
applications. The PHY supports 10/100/1000 Mbps operation with RGMII
interface and includes features such as IEEE 802.3az Energy Efficient
Ethernet, IEEE 1588 SyncE.

The driver implements extended register access via indirect addressing
(registers 0x1E/0x1F) and provides comprehensive device tree support
for RGMII delay configuration. The rx-internal-delay-ps and
tx-internal-delay-ps properties allow precise tuning of clock delays
in 150 ps steps from 0 to 2250 ps.

This PHY is used on the NDA platform with 1G Ethernet tile and has
been tested on that hardware with successful link establishment and
RGMII delay tuning.
