iMAC with Broadcom 14e4-1686 BCM57766 : link status down

Bumping this post as we seem to have another one here https://forums.fogproject.org/topic/9278...ac-netboot

iMac17,1 (Late 2015 model) as well as iMac14,1 with the same ethernet chip. Find more details in the FOG forum posts. I guess it's best to focus on that iMac17,1 model first. If we can get this to work the other one might be fixed as well.

We have of Macmini6,2 with the same ethernet chip (same PCI IDs) proof working:

Possibly the issue is with net1 interface (wireless adapter AFAIK) being initialized first and then net0 (ethernet)?!

@marcolefo You might want to add even more debugging with DEBUG=tg3,tg3_hw,tg3_phy
