i40e X710 tx ring disable timeout

[shieldengr]

We have a custom XDP AF_Packet application that monitors network traffic.  Prior to starting our application, we bring down the X710 interface and back up.

On one field system, we are seeing consistent errors when we do this while traffic is flowing.    The effect is the card stops observing traffic and sometimes loses link.

These errors usually begin with

   i40e 0000:8a:00.0: VSI seid 390 Tx ring 65 disable timeout

And are usually followed by

    kernel: i40e 0000:8a:00.1: HMC error interrupt

    kernel: i40e 0000:8a:00.1: HMC error info 0x80100301, HMC error data 0x40

We have replaced the X710 card with another X710 card in this system and still see the issue.  We have not been able to replicate the issue on any other system.

The two adapters tried are: Ethernet Controller X710 for 10GbE SFP+

  # ethtool -i ens1f0
  driver: i40e
  version: 2.8.20-k
  firmware-version: 6.00 0x800062c5 18.5.17

  # ethtool -i ens1f0
  driver: i40e
  version: 2.8.20-k
  firmware-version: 8.30 0x8000ab72 1.2926.0

Hello shieldengr,

Thank you for posting in Intel Ethernet Communities. 

Please provide the following information that would help in checking your query. 

1. Exact Operating System used

2. Brand and model of the system where the cards were installed. This is just for our record purposes only.

3. When you mentioned, we have replaced the X710 card with another X710 card in this system and still see the issue. We have not been able to replicate the issue on any other system, does this mean that the issue is specific to only one of your system?

4. Please share the PBA of the adapter. You may refer to the link below on where to find the PBA number. The PBA consists 6-3 digit number located at the last part of the serial number. This would help us identify if you are using an Original Equipment Manufacturer(OEM) or retail version of Intel Ethernet Adapter.

1. Operating System - Fedora linux with 5.6.6 kernel

2. Brand of system - Supermicro SYS-110P-WTR

3. Correct, we have many of these same systems in production but this issue only occurred on a particular system at one site and we have not been able to reproduce on any other systems.

4. We are not physically onsite to get the PBA of the adapter sticker.  Is there a way it can be queried from within Linux?
