Hello, I'm struggling to understand why it takes a lot of time to boot till we get ping success. We use system with i210 , and igb driver. I use dmesg for time measurement( and gpios to sync dmesg timing with board power time)
This is dmesg with added prints for each IGB function enter and exit time: https://drive.google.com/file/d/1Zdxp_fljawrzpuM4Q0at5YH6yOahoSse/view?usp=sharing I see that driver use some watchdog to decide if link is up (as can be seen in the above log), yet I don't understand why it takes so long from kernel start till ping success. Even when link is up it still take a long interval from link up till ping success, as you can see in the log file. I can't disable auto-negotiation because we need to use 1Gb. Is there anything else I can do ? Thank you, ranran
