FOG & iPXE Configuring net0... slowly

Always try latest master as described above. The reason for testing these known builds is to also know that it is not any kind of build config that is causing issues.

We still don't know what you are booting in terms of undionly.kpxe or ipxe.pxe (assuming you are booting in legacy mode)
For intel nics you could also use intel.pxe, other variants is not recommended.

When we know a bit more you could then build iPXE with debug flags enabled...
For example if you are using ipxe.pxe then building with make bin/ipxe.pxe DEBUG=intel will give intel specific debug output which could give you information about what the nic does. Then switching to DEBUG=intel,dhcp would also show DHCP related debug messages.
