While setting PTP on an ST box with 4.00a Ethernet core, the kernel panics due to a broken settings of the descriptors. The patches review the register configuration, the algo used for configuring the protocol, the way to get the timestamp inside the RX/TX descriptors and, in the end, the statistics displayed by ethtool.
