We already got working card with same chip (Selecom) and decided to purchase another one - but Intel branded XL710-QDA2.
After deploying and upgrading firmware and driver to the latests versions, we found that 40gbit/s link is up and icmp (pings) packets go perfectly, but there is no ability to set up any TCP connection.
Ethtool shows a lot of rx_crc_errors on this interface.
We've tested it with two brand new Intel cables and got the same result.
What can be reason of this?
i40e version 1.5.18
nvm version 5.0.4

Hi AlexanderKlimenko,
Can you provide me the serial number of the network adapter and the marking on the box?
Serial number can be found on the white sticker barcode with 15 digits + 6 digits + 6-3 digits
What is the exact product code and MM# ?
What is also the exact Intel cable model used?
Thanks,
wb

Unfortunately we don't have a box of this card because it was the replacement of /thread/99976 B0 version. Seller provided new adapter in a box of the old one.
We can't provide cable model information at the moment (located in a remove DC). Is there any way to extract it remotely by the software? If not going to get it in few days.

We've got XLDACBL5 40G Qsfp+ cable. It was working perfectly with B0 before it was upgraded with latest firmware and replaced by seller.

Hope it won't take much time, because we are at the end of warranty period at the moment.

Hi AlexanderKlimenko,
I will update you as soon as there is any finding. Are you referring to the network adapter warranty period? XL710-QDA2 covered a limited lifetime warranty.

Hi AlexanderKlimenko,
Can you help confirm below information for us to better investigate on this:
1) When you said unable to establish TCP connection, is it based from not able to do file transfer or intermittent web browsing?
2) Have you tried out 10Gbps connection to see if there is also the rx crc error?
Thanks,
wb

Any tcp connection fails including wget, curl, telnet, ssh, tcp-dns etc.

We were interested in 40gb link, so we didn't. Need some time to take consultations and testing.

Hi AlexanderKlimenko,
Thank you for the clarification.
For the TCP connection, were you able to connect to internet ?
And how many units of XL710 were affected with this issue?
What happens if connection is peer to peer or back to back?
Di you try using tool other than ethtool? What is the result?

I've already provided 3 of 4 answers for your previous post and I don't understand why it was removed from public access.
Just got the replacement from the seller with exactly same problem. We have few days to test it again before it sent back.
Going to test back-to-back configuration tomorrow.
> For the TCP connection, were you able to connect to internet ?
No, as I've noticed above all TCP connections (wget, curl, telnet, ssh, tcp-dns etc.) fail.
The only packets we got successfully transmitted - were pings.
> And how many units of XL710 were affected with this issue?
We got 2 cards with the same family chip. One is Intel branded and the other - Silicom. After a lot of manipulations we've got both working on 40gb.
After firmware upgrade Intel one stopped - because it was B0 version. After replacement we weren't able make it working again.
So only one.
*** And one new replaced by the seller!
> What happens if connection is peer to peer or back to back?
We don't have ability to check it at the moment, because the second card we got is installed in production server.
We tried connecting the other router and port (worked with other and previous card) - with same result. So don't think there could be difference.
> Di you try using tool other than ethtool? What is the result?
What tool? Tried to do what?
To see errors? Without type clarification, it could be seen with ifconfig.

Hi AlexanderKlimento,
Thank you for the update. Please update us the back to back connection test.
Just want to clarify are you referring the Intel X710 NIC is not working after the firmware upgrade so you will be testing only the one with the Silicom?
As mentioned "We tried connecting the other router and port (worked with other and previous card) - with same result. So don't think there could be difference." Are you referring the Intel X 710 NIC connected to other router and port has the same issue of having rX_CRC error on the interface?
