How does iPXE assign a network interface to net0?

It will be the first device enumerated by iPXE, which will generally mean the lowest-numbered PCI device in the system.

You can find out various characteristics of the physical device by using the ${pci/....} settings. For example:

Code:

echo net0 has IDs ${pci/${net0/busloc}.0.2}:${pci/${net0/busloc}.2.2}

More examples available at http://ipxe.org/cfg/busloc.
