This was fixed by the following patch series which have parts that get merg= ed along the way to version 21. It adds support to select the hardware PTP provider and change the default to MAC PTP for newly introduced PHY PTP sup= port (default_timestamp flag in phy_device struct). https://lore.kernel.org/netdev/20241212-feature_ptp_netnext-v21-0-2c282a941= 518@bootlin.com/ I will add the description in v3. I will wait at least one week to let peop= le review the patch. Regards, --=20 K=C3=B6ry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
