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)

Merge branch 'net-add-adin1140-support'

Ciprian Regus says:

====================
net: Add ADIN1140 support

This series introduces support for the ADIN1140 (also called AD3306)
10BASE-T1S single port MACPHY. The device integrates the MAC and PHY in
the same package. The communication with the host CPU is done through an
SPI interface, using the Open Alliance TC6 protocol for control and data
transactions. As a result, the oa_tc6 framework is used to implement
the communication with the device (register accesses and Ethernet frame
RX/TX).

The MAC and PHY are connected internally using an MII and MDIO bus.

The PHY is a half duplex 10Mbps device, which implements both the PLCA
RS (IEEE 802.3 clause 148) and CSMA/CD methods of accessing the Ethernet
medium. The 10BASE-T1S standard allows multiple PHY devices to be
connected (in parallel) on the same single twisted pair network segment,
so PLCA can be configured in order to provide a fair access scheme to
all the nodes and reduce the jitter introduced by the unordered CSMA/CD
transmits. The PHY's internal register map can be accessed using the
direct MDIO mode of the OA TC6. The control, status, phy id 1 & 2 C22
registers are mapped to the 0xFF00 - 0xFF03 range. As for C45
addressable devices, the PHY has PCS, PMA and PLCA blocks.

The oa_tc6 framework patches are changes that would make the library
usable by the subsequent ADIN1140 MAC driver.

The protected mode patch is required because the ADIN1140 only allows
protected mode OA TC6 control transactions, which the oa_tc6 framework
doesn't currently implement.

The OA_TC6_BROKEN_PHY quirk patch is required in order to allow the MAC
driver to have a custom implementation for the mii_bus access methods as a
workaround for hardware issues:

1. The OA TC6 standard defines the direct and indirect access modes for
MDIO transactions. The ADIN1140 incorrectly advertises indirect mode
only (supported capabilities register - 0x2, bit 9), while actually
implementing just the direct mode. We cannot rely on the CAP register
to choose an access method (which oa_tc6 does by default, even though
it only implements the direct mode), so the driver has to use its
own.
2. The ADIN1140 cannot access the C22 register space of the internal
PHY, while the PHY is busy receiving frames. If that happens, the
CONFIG0 and CONFIG2 registers of the MAC will get corrupted and the
data transfer will stop. Those two registers configure settings for
the transfer protocol between the MAC and host, so the value for some
of their subfields shouldn't be changed while the netdev is up.
Since we know the PHY is internal, the MAC driver can implement a
custom mii_bus, which can intercept C22 accesses. Most of the
registers mapped in the 0x0 - 0x3 range (the only ones the PHY offers)
are read only, and their value can be read from somewhere else (e.g
the PHYID 1 & 2 have the same value as 0x1 in the MAC memory map).
C45 accesses do not cause this issue, so we can properly implement
them.

Even though they have different driver, the MAC one cannot function
without the PHY driver, since the PHY is not compatible with the generic
c22 driver. As such CONFIG_ADIN1140 selects CONFIG_ADIN1140_PHY.

net: phy: Add support for the ADIN1140 PHY

Add a driver for the ADIN1140's internal 10BASE-T1S PHY. The device
doesn't implement autonegotiation, so the link is always reported as
being up.

The device implements both C22 and C45 MDIO access methods, but can only
be discovered over C22, since the C45 MMD devices lack the MDIO_DEVID1 and
MDIO_DEVID2 registers. The indirect C45 over C22 feature is not
supported.
