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.
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:
[ 2.538089] igb: Intel(R) Gigabit Ethernet Network Driver network 5
- version 5.4.0-k
[ 2.549736] network igb_reset

[ 5.216208] network igb_phy_has_link
[ 7.881180] network igb_phy_has_link
Is there any idea how to minimize igb boot time ?

Sorry, no idea. You may have more luck if you ask on the kernel netdev

I use igb driver.
Spanning tree protocol on the connected switch might be causing it.
