That's your ethernet device. The 'not configured' message means there is no driver support in OpenBSD for this device yet. It looks like Linux has a driver for it, called alx. FreeBSD does not have a driver for this device either. It's possible that an entirely new driver must be written to make this device work with OpenBSD. So this will take time and more importantly someone who has the skill and motivation to write it. For now, you'll be happier using a supported USB ethernet adapter. The axen(4) driver supports models currently being sold. Some model names are listed here: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man4/axen.4?query=axen Or perhaps you can still find an older model supported by axe(4): http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man4/axe.4?query=axe Another option are devices supported by the generic USB Ethernet device driver cdce(4). These devices use a standard USB interface so a custom driver is not required. Apart from devices listed at http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man4/cdce.4?query=cdce the "Lenovo Thinkpad USB 3.0 Ethernet adapter" will also work with this.
