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

Wed Oct 17 18:01:03 UTC 2018

Hi,

I can confirm that PTP is NOT supported on X550 VF device.
It works when one port is in pass-through mode as this is a PF device being mapped into the VM and not VF.

You can see in the ixgbevf driver that SIOCSHWTSTAMP ioctl is not handled.
There is no plan for PTP support for ixgbevf as for now.

Thanks, Tim

Hello,

As far as I know, PTP is not (and probably will not be) supported by VF driver.

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)
