From 35f7cad1743e04bf2944a2aadb6b6a42adc57bca Mon Sep 17 00:00:00 2001 From: Kory Maincent Date: Thu, 12 Dec 2024 18:06:43 +0100 Subject: net: Add the possibility to support a selected hwtstamp in netdevice Introduce the description of a hwtstamp provider, mainly defined with a the hwtstamp source and the phydev pointer. Add a hwtstamp provider description within the netdev structure to allow saving the hwtstamp we want to use. This prepares for future support of an ethtool netlink command to select the desired hwtstamp provider. By default, the old API that does not support hwtstamp selectability is used, meaning the hwtstamp provider pointer is unset. Signed-off-by: Kory Maincent Signed-off-by: David S.

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.
