[PATCH net-next RFC V1 0/5] Peer to Peer One-Step time stamping

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.

Earlier today I posted user space support as an RFC on the
linuxptp-devel list. Comments and review are most welcome.

Thanks,
Richard
