The KSZ9131RNX incorrectly shows EEE capabilities in its registers.
Although the "EEE control and capability 1" (Register 3.20) is set to 0,
indicating no EEE support, the "EEE advertisement 1" (Register 7.60) is
set to 0x6, advertising EEE support for 1000BaseT/Full and
100BaseT/Full.
This inconsistency causes PHYlib to assume there is no EEE support,
preventing control over EEE advertisement, which is enabled by default.
This patch resolves the issue by utilizing the ksz9477_get_features()
function to correctly set the EEE capabilities for the KSZ9131RNX. This
adjustment allows proper control over EEE advertisement and ensures
accurate representation of the device's capabilities.

dp83869 internally uses a look-up table for mapping supported delays in
nanoseconds to register values.
When specific delays are defined in device-tree, phy_get_internal_delay
does the lookup automatically returning an index.
The default case wrongly assigns the nanoseconds value from the lookup
table, resulting in numeric value 2000 applied to delay configuration
register, rather than the expected index values 0-7 (7 for 2000).
Ultimately this issue broke RX for 1Gbps links.
Fix default delay configuration by assigning the intended index value
directly.

Andrew reports that the SFF modules on one of the ZII platforms do not
indicate link up due to the SFP code believing that LOS indicating that
there is no signal being received from the remote end, but in fact the
LOS signal is showing that there is signal.
What makes SFF modules different from SFPs is they typically have an
inverted LOS, which uncovered this issue. When we read the hardware
state, we mask it with state_hw_mask so we ignore anything we're not
interested in. However, we don't re-read when state_hw_mask changes,
leading to sfp->state being stale.
Arrange for a software poll of the module state after we have parsed
the EEPROM in sfp_sm_mod_probe() and updated state_*_mask. This will
generate any necessary events for signal changes for the state
machine as well as updating sfp->state.

falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review

Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.

- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit

useful when dynamically determining the devices features does not
work, e.g. support of fibre.
EEE support has been moved into phydev->supported_eee. This needs to
be set otherwise the code assumes EEE is not supported. It is normally
set as part of reading the devices abilities. However if a static

performed. Add a call to genphy_c45_read_eee_abilities() to read the

- this functionality is for devices implementing parts of IEEE 802.3
specification beyond Clause 22. The better place for this code is
phy-c45.c
- currently it is able to do read/write operations on PHYs with
different abilities to not existing registers. It is better to
use stored supported_eee abilities to avoid false read/write
operations.
- the eee_active detection will provide wrong results on not supported
link modes. It is better to validate speed/duplex properties against
supported EEE link modes.
- it is able to support only limited amount of link modes. We have more
