net: ethtool: add get_rx_ring_count callback to optimize RX ring queries

2025-09-18T14:07:37+00:00

Add a new optional get_rx_ring_count callback in ethtool_ops to allow drivers to provide the number of RX rings directly without going through the full get_rxnfc flow classification interface. Create ethtool_get_rx_ring_count() to use .get_rx_ring_count if available, falling back to get_rxnfc() otherwise. It needs to be non-static, given it will be called by other ethtool functions laters, as those calling get_rxfh().

ethtool: rejig the RSS notification machinery for more types

2025-07-22T01:20:19+00:00

In anticipation for CREATE and DELETE notifications - explicitly pass the notification type to ethtool_rss_notify(), when calling from the IOCTL code. Reviewed-by: Gal Pressman Link: https://patch.msgid.link/20250717234343.2328602-3-kuba@kernel.org Signed-off-by: Jakub Kicinski

ethtool: rss: support setting input-xfrm via Netlink

2025-07-17T23:13:59+00:00

Support configuring symmetric hashing via Netlink. We have the flow field config prepared as part of SET handling, so scan it for conflicts instead of querying the driver again.

net: ethtool: rss: add notifications

2025-06-25T22:24:14+00:00

In preparation for RSS_SET handling in ethnl introduce Netlink notifications for RSS. Only cover modifications, not creation and not removal of a context, because the latter may deserve a different notification type. We should cross that bridge when we add the support for context add / remove via Netlink. Link: https://patch.msgid.link/20250623231720.3124717-7-kuba@kernel.org Signed-off-by: Jakub Kicinski

net: ethtool: Export the link_mode_params definitions

2025-03-18T08:03:11+00:00

link_mode_params contains a lookup table of all 802.3 link modes that are currently supported with structured data about each mode's speed, duplex, number of lanes and mediums. As a preparation for a port representation, export that table for the rest of the net stack to use.

net: ethtool: fix ioctl confusing drivers about desired HDS user config

2025-02-24T22:15:42+00:00

The legacy ioctl path does not have support for extended attributes. So we issue a GET to fetch the current settings from the driver, in an attempt to keep them unchanged. HDS is a bit "special" as the GET only returns on/off while the SET takes a "ternary" argument (on/off/default). If the driver was in the "default" setting - executing the ioctl path binds it to on or off, even tho the user did not intend to change HDS config. Factor the relevant logic out of the netlink code and reuse it.

net: ethtool: tsconfig: Fix netlink type of hwtstamp flags

2025-02-07T00:35:21+00:00

Fix the netlink type for hardware timestamp flags, which are represented as a bitset of flags. Although only one flag is supported currently, the correct netlink bitset type should be used instead of u32 to keep consistency with other fields. Address this by adding a new named string set description for the hwtstamp flag structure. The code has been introduced in the current release so the uAPI change is still okay.

net: ethtool: tsinfo: Enhance tsinfo to support several hwtstamp by net topology

2024-12-16T12:51:41+00:00

Either the MAC or the PHY can provide hwtstamp, so we should be able to read the tsinfo for any hwtstamp provider. Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a network topology. Add support for a specific dump command to retrieve all hwtstamp providers within the network topology, with added functionality for filtered dump to target a single interface.
