Changed in v2: ~~~~~~~~~~~~~~ - Per the v1 review, changed the modeling of MII time stamping devices. They are no longer a kind of mdio device. This series adds support for PTP (IEEE 1588) P2P one-step time stamping along with a driver for a hardware device that supports this. If the hardware supports p2p one-step, it subtracts the ingress time stamp value from the Pdelay_Request correction field. The user space software stack then simply copies the correction field into the Pdelay_Response, and on transmission the hardware adds the egress time stamp into the correction field. - Patch 1 adds the new option. - Patches 2-4 adds support for MII time stamping in non-PHY devices. - Patch 5 adds a driver implementing the new option. User space support is available in the current linuxptp master branch.
