Btw, we did hit one issue in the backport. We started to get rx csum
faults (checksum complete value indicates TCP checksum is bad, but
host computation says checksum is good). I ran against 4.9 upstream
kernel and do see these, however don't see them in 4.10. I haven't
bisected yet. Is this a known issue?
Not to me, I don't recall any csum related fixes or feature submitted
lately to mlx5,
Maybe something changed in the stack ?
what configuration are you running ? what traffic ?
Nothing fancy. 8 queues and 20 concurrent netperf TCP_STREAMs trips
it. Not a lot of them, but I don't think we really should ever see
these errors.
Hi Tom
I've been trying to repro with no luck with kernel v4.9.
I am looking for checksum errors in dmesg, is that the place where you
saw the errors ?
can you dump the error in here ?
