Hello

According to your guidance, we have successfully compiled the PFE server and firmware into the kernel. The loading speed of the PFE driver has indeed increased, but we have discovered an issue where PFe1 and PFe2 set their MAC addresses after 10 seconds. What is the reason for this? And report Driver runtime error at 2.433127 seconds? Does PFE support sleep wake-up?

Thank you! Looking forward to your reply
