If it's just providing a read of an accurate timesource, I think it's kinda pointless to provide a full PTP driver for it. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
