Hello,

we found regression on intel card(XL710) with i40e driver.
Regression is
about ~45%
on TCP_STREAM and TCP_MAERTS test for IPv4 and IPv6. Regression
was first
visible in kernel-4.12.0-0.rc1.

More details about results you can see in uploaded images in
bugzilla. [0]

I have added the i40e driver maintainer and the intel-wired-lan
mailing list so that we can make are developers aware of the issue.

Thanks.

Adam,

We are having some issues trying to reproduce what you reported.

Can you provide some additional data. Specifically we would be
looking
for an "ethtool -i", and an "ethtool -S" for the port before and
after
the test. If you can attach it to the bugzilla that would be
appreciated.

Thanks.
