Hi all,
This series aims to add two-step PTP support for the KSZ8463 driver. It
depends on a previous series that was recently applied to net-next:
https://lore.kernel.org/all/20260105-ksz-rework-v1-0-a68df7f57375@bootlin.com/
I've encountered weird behavior with IPv4 and IPv6 layers -- maybe that's
related to the incompatibility with the Linux stack mentionned by commit
620e2392db235 ("net: dsa: microchip: Disable PTP function of KSZ8463") ? --
So the support is only added for the L2 layer.
Patches 1 to 4 add IRQ support for the KSZ8463
Patch 5 adds specific dsa_device_ops for the KSZ8463
Patches 6 to 8 add PTP support for the KSZ8463
