Thanks Yairi.
To make sure I understand:
ConnectX3 supports ethernet timestamping, but does NOT support the timestamps in the VF.
ConnectX4 supports ethernet timestamping and it supports timestamps in the VF.
Is this correct or was there a typo above?
The Mellanox Linux Users Manual says that only ConnectX3 supports ethernet timestamping, so I am checking if I missed something.
