[Intel-wired-lan] X550 VF do not support PTP

[Henning Svane]

Hi

I cannot get PTP hardware to work on a Virtual Function Ethernet Controller.
Here below you can see what I have tried with no luck.

How can I enable PTP hardware on Virtual function NIC, as from what I can read in the documentation this should work, but how?

As hypervisor I use VMware ESXi 6.7 (9484548)

Regards
Henning

On Ubuntu 18.04.1 (4.15.0-34-generic)
I am trying to get PTP to work on a X550 dual port, which has been setup so one port is SR-IOV (24 VF) and the other as Passthrough.

04:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
0b:00.0 Ethernet controller: Intel Corporation X550 Virtual Function
13:00.0 Ethernet controller: Intel Corporation X550 Virtual Function

To be sure that the drive support PTP I downloaded the newest driver
ixgbevf-4.3.5.tar.gz
sudo make CFLAGS_EXTRA="-DIXGBE_PTP" install (The documentation says this options has to be set)

Ens161 is the Passthrough NIC and here PTP works.
