I found reference to mbuf’s timestamp field only in MLX5. I think it is the only one to support timestamp offloading. This new API is only useful to make sense out of the timestamp value. And without this patch, timestamp offloading is completely useless…
What would be the other way ? Define something in mlx5 header and ask clients to check for the driver and call the specific API ?
I see reference to timestamp offloading in Netronome Agilio, CC-ing maintainers. Is timestamp offloading a feature you could potentially provide ? Would it be host time reference or a value that need conversion with an API like this?
