Hello I would like to know how the kernel is naming the network interfaces. I have a automated installation for Rhel with predefined network interface names for the dedicated hardware. I would like to know if I change one NIC card if this names are going to change.
I found this: The kernel detects device hardware locations in terms of PCI bus number, slot number, and device number. That will not change unless you unplug it and move it to a different expansion slot. The new names are based on these physical parameters, and so they do not change from one boot session to the next.
but I am not sure what they mean with device number. Is this NIC's Mac address stored in the ROM? If yes than it will probably change the names of the network interfaces
