<p>I added this because the DHCPv6 client was complaining about the lack of IID on the downstream interface. I also think some things (router solicitation?) would not work properly if the interface had no link-local address.</p>

<p>If you need an address for your connection over UART/USB why not use ethos or usb_acm_ecm instead?</p>

<p>This was to connect multiple boards together using SLIP. Each board has two SLIP interfaces.</p>
