The stack assumed that PHY time stamping is always preferred, but some MAC/PHY combinations were buggy. This series updates the default MAC/PHY default timestamping and aims to allow the user to select the desired hwtstamp provider administratively. Changes in v8: - Drop the 6 first patch as they are now merged. - Change the full implementation to not be based on the hwtstamp layer (MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a phc qualifier. - Made some patch to prepare the new implementation. - Expand netlink tsinfo instead of a new ts command for new hwtstamp configuration uAPI and for dumping tsinfo of specific hwtstamp provider. - Link to v7: https://lore.kernel.org/r/20231114-feature_ptp_netnext-v7-0-472e77951e40@bootlin.com Changes in v7: - Fix a temporary build error. - Link to v6: https://lore.kernel.org/r/20231019-feature_ptp_netnext-v6-0-71affc27b0e5@bootlin.com Changes in v6: - Few fixes from the reviews. - Replace the allowlist to default_timestamp flag to know which phy is using old API behavior. - Rename the timestamping layer enum values. - Move to a simple enum instead of the mix between enum and bitfield. - Update ts_info and ts-set in software timestamping case. Changes in v5: - Update to ndo_hwstamp_get/set. This bring several new patches. - Add few patches to make the glue. - Convert macb to ndo_hwstamp_get/set. - Add netlink specs description of new ethtool commands. - Removed netdev notifier. - Split the patches that expose the timestamping to userspace to separate the core and ethtool development. - Add description of software timestamping. - Convert PHYs hwtstamp callback to use kernel_hwtstamp_config. Changes in v4: - Move on to ethtool netlink instead of ioctl. - Add a netdev notifier to allow packet trapping by the MAC in case of PHY time stamping. - Add a PHY whitelist to not break the old PHY default time-stamping preference API. Changes in v3: - Expose the PTP choice to ethtool instead of sysfs. You can test it with the ethtool source on branch feature_ptp of: https://github.com/kmaincent/ethtool - Added a devicetree binding to select the preferred timestamp. Changes in v2: - Move selected_timestamping_layer variable of the concerned patch. - Use sysfs_streq instead of strmcmp. - Use the PHY timestamp only if available.
