Subject: [Intel-wired-lan] PTP hardware timestamping on E810 VF
Date: Wed, 16 Nov 2022 16:39:13 +0200	[thread overview]
Message-ID: <48e8a46e-2c74-22be-e95b-dd0d67ea2012@asocscloud.com> (raw)

Hi,

I wonder how can I enable PTP HW timestamping on E810 *VF*. It is 
supported on the PF, but looks like not on the VF. At the same time, 
ESXi manual says that it is supported on VFs as well 
(https://docs.vmware.com/en/VMware-Telco-Cloud-Automation/2.1.1/com.vmware.tca.userguide/GUID-57C099A3-78E7-4B94-BF54-AD0D6C2EF175.html)

Is it supported only on ESXi, but not on Linux? Any ideas?

# ethtool -T ens3f0  # <== PF
Time stamping parameters for ens3f0:
Capabilities:
	hardware-transmit
	software-transmit
	hardware-receive
	software-receive
	software-system-clock
	hardware-raw-clock
PTP Hardware Clock: 3
Hardware Transmit Timestamp Modes:
	off
	on
Hardware Receive Filter Modes:
	none
	all

# ethtool -T ens3f0v0  # <== VF
Time stamping parameters for ens3f0v0:
Capabilities:
	software-receive
	software-system-clock
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none


Thanks,
Leonid.
