To configure your network interface on the workstation side, we need
to know the name of the network interface connected to your board.
-However, you won't be able to see the network interface corresponding
-to the Ethernet over USB device connection yet, because it's only active when
-the board turns it on, from U-Boot or from Linux. When this
-happens, the network interface name will be \code{enx<macaddr>}.
-Given the value we gave to \code{usbnet_hostaddr}, it will
-therefore be \code{enxf8dc7a000001}.
+Note that when the board is sitting at the U-Boot prompt, no network
+interface will show up on the workstation side. It is only when U-Boot
+is actively executing a network-related command (such as \code{ping}
+or \code{tftp}) that it brings up the USB network connection.
+
+From the board, run \code{ping 192.168.0.1}, and while the \code{ping}
+command is running, you should see on your workstation a new network
+interface named \code{enx<macaddr>}. Given the value we gave to
+\code{usbnet_hostaddr}, it will therefore be
+\code{enxf8dc7a000001}. Note that pinging the board from your PC will
+not work: when U-Boot is sitting at its prompt, it is not able to
+reply to ping requests.
Then, instead of configuring the host IP address from NetWork Manager's
graphical interface, let's do it through its command line interface,
