Solarflare network card disconnection leading to bond1 network card switch

[liuchaowhu]

We experienced a network card port disconnection on a server equipped with a Solarflare low-latency network card at around 07:41 this morning. Attached are the relevant logs. Please help analyze the cause of the issue. Thank you.

Environment Information:

Hardware: Lenovo SR650 server + Solarflare network card

Operating System: RHEL 7.9 + Kernel 3.10.0-1160.66.1.el7.x86_64

​
Symptoms:

On the same Solarflare network card, two ports (workbeA and ens1f0) experienced simultaneous port disconnection (automatically recovered after 2 seconds). The port workbeA is used for business (connected to optical fiber), and the port ens1f0 is an idle port (not connected to optical fiber). No actions were taken before or after the disconnection, and the "onload" functionality is not currently enabled. The system uses the Solarflare version 4.1 driver provided by Red Hat. We are investigating the network card disconnection issue and would like to confirm whether there is a bug in the currently used Solarflare network card driver or firmware based on the provided system logs and sfcrepor
