S32G PFE pfeng module: how to suppress “Mismatch between static L2 bridge entry and frame inbound po

Hello,

I am using NXP S32G PFE on Linux and configuring the bridge through libfci_cli.

My current network setup includes an additional external router/switch, so in some cases the following log message is generated repeatedly during bridge operation:

[10017.573092] pfeng 46000000.pfe: PE1: fp_l2_bridge.c line 736: Mismatch between static L2 bridge entry and frame inbound port

What I want is not to solve the bridge topology itself, but simply to suppress this log message because it is flooding the terminal/log output in my use case.

I would like to ask the following:

1. Is there any official runtime option provided by NXP to suppress this specific PFE/pfeng log message?
   • module parameter
   • debug/log level option
   • kernel boot argument
   • libfci_cli related option
2. If there is no runtime option, is this log generated by:
   • Linux pfeng kernel module side, or
   • PFE firmware side?
3. If source modification is required, which part should be modified?
   • exact source file
   • log macro/function used for this message
   • recommended way to disable only this message

For reference:

• I am using libfci_cli commands only, not a custom-built application.
• The message appears while using static L2 bridge entries.
• Because of the external router/switch in the test environment, this condition can occur and is expected in my setup.
• My goal is only to hide/suppress the message, not to change bridge behavior.

If needed, I can also provide:

• libfci_cli bridge configuration
• bd-print / phyif-print output
• kernel version
• pfeng module information

Thank you.

Hello,

Thank you for your reply.

1. The PFE version I am using is 1.10.0.
2. Yes, I am using the PFE on the A core only as Master.

Please let me know if you need any additional information.

Thank you.

Hi，minJ

Thank you for contacting us. Could you share more information with me?

1.What is your PFE/BSP version?

2.Do you use the PFE on A core only as Master?

Hi,minJ

Thank you for your reply.

1.You can try to modify the file of pfeng to disable the log output.

sw\pfe_platform\public\pfe_log_if.h

sw\pfe_platform\src\pfe_log_if.c

2.You can use this command to filter this error message in Kernel.

dmesg -w | grep -v "Mismatch between static L2 bridge entry and frame inbound port"

3.Also, you can share your L2 configuration with me, can help me try to produce your question, but it will take some time for the testing. 

libfci_cli bridge configuration
bd-print / phyif-print output

Hope this information can help you.
