Is there any update on that subject?
There is no much time left before 17.02 integration deadline, and we sort of stuck
because there is luck of response from ENA device maintainers.
Could you at least point to some sort of spec for that device,
or might be to some people who might answer that question?
From what I can see looking at Linux ENA driver, it is not doing anything special for TSO.
So it seems that standard pseudo-header checksum calculation should be enough.
Is that correct?
Thanks
