Sets the PC to 10.0.0.50/24 so the GC test suite's RX test can pass: its TX test ARPs for that address and the kernel answers ARP for an address it actually holds, so no listener process is needed. Without it RX fails legitimately for lack of traffic. Handles the NetworkManager trap -- NM silently strips a hand-added address within seconds, so the device is set unmanaged first and handed back on 'down'. Warns that this drops any existing connection on that NIC. up / down / status / watch, with wired-interface auto-detection (prefers one with a carrier) and a status readout that flags no-carrier along with the likely cause: the W5100S rail is gated off GC_ON, so it is dead whenever the console is off.
