From version 3.2.1 sfptpd can recover hardware timestamps for PTP packets from third party adapters. sfptpd will also discipline the clocks on third party adapters that support the PHC API.

This is an experimental feature where testing has shown that synchronization accuracy/performance in mixed adapter systems is best on Xilinx adapters.

Xilinx have conducted limited testing with a range of third party adapters. The list of tested models can be found in the sfptpd Release Notes.

Note: Implementation of the PHC API is not uniform across all third party adapters, therefore this is a best effort feature.
