Hello,

This is not specific buildroot issue, yet I hope someone here will have an
idea.
I have long ethernet boot time till receiving ping after powerup.
I use igb driver.


Spanning tree protocol on the connected switch might be causing it.



I tried plenty of things, but nothing worked.
I have printed the function which are called in igb driver.

This is the relevant log in dmesg:

Is there any idea how to minimize igb boot time ?
