It is worth to remember that native Ethernet interface is still available for U-Boot operations. As such, Linux kernel image and device tree blob can be retrieved by target over native Ethernet connection (that's why this cable has not been disconnected). Once Linux kernel gets the control of the processor, it initializes the USB/Ethernet port - that is mapped as <code>eth0</code> - that is the only one available in the Linux realm.
