Re: [PATCH net-next 5/5] selftests: net: add veth BQL stress test

Hi, thanks for your work! I am really interested in this patchset.

I am planning to submit a similar patch set (see [1]) for the tun/tap
driver, where I am currently implementing qdisc backpressure similar
to that used in veth.

Can you run pktgen [2] to see if there is a regression?
I think that there might be a slowdown due to BQL not choosing a big
enough queue size.

Thanks!
