netlink: specs: add the multicast group name to spec

2025-06-25T22:24:13+00:00

Add the multicast group's name to the YAML spec.
Without it YNL doesn't know how to subscribe to notifications.

net: ethtool: remove duplicate defines for family info

2025-06-18T21:10:39+00:00

Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.

Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.

Provide naming info in YAML and remove the incorrect defines.

net: ethtool: add support for structured PHY statistics

2025-01-14T10:44:19+00:00

Introduce a new way to report PHY statistics in a structured and
standardized format using the netlink API. This new method does not
replace the old driver-specific stats, which can still be accessed with
`ethtool -S `. The structured stats are available with
`ethtool -S  --all-groups`.

This new method makes it easier to diagnose problems by organizing stats
in a consistent and documented way.

ethtool: separate definitions that are gonna be generated

2024-12-05T20:03:04+00:00

Reshuffle definitions that are gonna be generated into
ethtool_netlink_generated.h and match ynl spec order.
This should make it easier to compare the output of the ynl-gen-c
to the existing uapi header. No functional changes.

Things that are still remaining to be manually defined:
- ETHTOOL_FLAG_ALL - probably no good way to add to spec?
- some of the cable test bits (not sure whether it's possible to move to
  spec)
- some of the stats definitions (no way currently to move to spec)

ethtool: Extend cable testing interface with result source information

2024-08-26T16:33:58+00:00

Extend the ethtool netlink cable testing interface by adding support for
specifying the source of cable testing results. This allows users to
differentiate between results obtained through different diagnostic
methods.

For example, some TI 10BaseT1L PHYs provide two variants of cable
diagnostics: Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD). By introducing `ETHTOOL_A_CABLE_RESULT_SRC` and
`ETHTOOL_A_CABLE_FAULT_LENGTH_SRC` attributes, this update enables
drivers to indicate whether the result was derived from TDR or ALCD,
improving the clarity and utility of diagnostic information.

net: ethtool: Introduce a command to list PHYs on an interface

2024-08-23T12:04:34+00:00

As we have the ability to track the PHYs connected to a net_device
through the link_topology, we can expose this list to userspace. This
allows userspace to use these identifiers for phy-specific commands and
take the decision of which PHY to target by knowing the link topology.

Add PHY_GET and PHY_DUMP, which can be a filtered DUMP operation to list
devices on only one interface.

net: ethtool: Allow passing a phy index for some commands

2024-08-23T12:04:34+00:00

Some netlink commands are target towards ethernet PHYs, to control some
of their features. As there's several such commands, add the ability to
pass a PHY index in the ethnl request, which will populate the generic
ethnl_req_info with the passed phy_index.

Add a helper that netlink command handlers need to use to grab the
targeted PHY from the req_info. This helper needs to hold rtnl_lock()
while interacting with the PHY, as it may be removed at any point.

ethtool: Add new result codes for TDR diagnostics

2024-08-16T17:16:16+00:00

Add new result codes to support TDR diagnostics in preparation for
Open Alliance 1000BaseT1 TDR support:

- ETHTOOL_A_CABLE_RESULT_CODE_NOISE: TDR not possible due to high noise
  level.
- ETHTOOL_A_CABLE_RESULT_CODE_RESOLUTION_NOT_POSSIBLE: TDR resolution not
  possible / out of distance.

ethtool: rss: support skipping contexts during dump

2024-08-12T13:16:24+00:00

Applications may want to deal with dynamic RSS contexts only.
So dumping context 0 will be counter-productive for them.
Support starting the dump from a given context ID.

Alternative would be to implement a dump flag to skip just
context 0, not sure which is better...

a call to pse_ethtool_set_pw_limit() to configure the PSE control power
