    X710-DA2 with i40e driver : PTP over UDP

    VolCoM

      Hello,

       

      I can read from : https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xl710-10-40-controller-spec-update.pd…  that :

       

      Starting from NVM image revision 5.05, the 710-series device does not process IEEE 1588 (TimeSync) PTP packets in the UDP payload. It only processes PTP packets using the Layer 2 packet format.

       

      Starting in NVM 6.01, this is supported.

      So the Firmware of the NIC apparently supports it since the start of 2018.

       

       

      I have been able to find in the changelog of the i40e driver from end 2016 :

      changelog for i40e-1.5.25

      ====================================

      * De-feature L3 (UDP) PTP frame detection and timestamping on XL710 devices.

        Support for L2 PTP frame detection and timestamping remains.

       

      But I can't find a recent driver changelog that says that the feature is back in the driver.

      Is the feature back in the driver or not yet ?

       

      Thank you.
