Hi, guys:
We encountered a PF reset issue at production environtment. The messages (Debian Linux) is like as below:
The driver/Nvm is like this 6.01/2.4.10:
According to intel, it is supposed to work well. But we have no luck.
Then we try to upgrade the driver to 2.14.13.
After running roughly one day, we got the error below.
Why did this happen?!
Any help or clue will be appreciated! Thank you.
Best wishes.

Hi doordie,
Thank you for posting in Intel Ethernet Communities.
In order for us to further investigate the issue, we would like addtional info such as below:
1) What is your system model and Debian version, kernel version?
2) Can you provide us more details of the NIC card model, please provide picture of the NIC card focusing on the markings on board.
The latest Intel generic firmware is V9.20 and the driver version 2.22.18. Have you try updating the drivers and firmware and see if the issues persist.
Notes: From your screenshot, NVM i40e (Linux)*1
*1 = These are out-of-tree versions.
Looking forward to your reply.
Thanks,
Irwan_Intel

Hi Irwan_intel:
Thank you for your reply.
1), We use brctl to create a virtual bridge consisting of two x710 ports to forward packets(No lacp). It's Debian 10.6 with kernel 4.20.1.
2), The Nic is this: "Ethernet Converged Network Adapter X710"
https://pci-ids.ucw.cz/read/PC/8086/1572
I tried the latest driver (2.22.18),but it's not supported by the kernel. See below:
Again, NVM/driver: 6.01/2.14.13. Here is some the messages.
I'm not sure if the mismatch of nvm&driver will still cause the up/down issue. Perhaps I should give it a try later.
Waiting for your reply.
Thank you.

Hi doordie,
According to our next level, I40e driver doesn't support Debian 10, and it's possible that the newest driver may not work as expected.
However, we suggest that you use the in-kernel Debian driver instead.
We also noticed that the NVM version you are currently using is quite old. Have you tried updating the NVM to see if that makes a difference? An updated NVM version can often resolve compatibility issues with newer drivers.
Please let us know if updating the NVM helps resolve your issue or if you have any further questions or concerns.
Regards,
Irwan_Intel

Hi Irwan_Intel,
Thanks a lot for your help. Last night we updated the NVM and everything looks fine until now. But what worries me is that the root cause of all the issues.
First of all, the nvm/driver should match each other according to the table offered by intel. It is not easy for me to know if it's a chip bug or not. Do you guys have methods to help us deal with these problems? Any analysing tools? At the very begining, we changed the wire and sfp modules.
BTW, there is anything new, we will let you know.
Thank you.
Regards,
doordie.

Hi, Irwan_Intel:
Thank you for asking. Actually we don't have any clue. But I did below on 21, April.
/sbin/ethtool -K ens1f0 tso off gro off gso off
/sbin/ethtool -K ens1f1 tso off gro off gso off
/sbin/ethtool -G ens1f0 rx 4096 tx 4096
/sbin/ethtool -G ens1f1 rx 4096 tx 4096
Don't know exactly the root cause, just try it. Everything is fine since then, we'll let you know if there is anythin new.
