With ifconfig(8)

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:0a:e4:23:e9:a9
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet6 fe80::20a:e4ff:fe23:e9a9%em0 prefixlen 64 scopeid 0x1
        inet 10.0.3.22 netmask 0xffffff00 broadcast 10.0.3.255

Some cheapo ethernet cards may have problem to report correct link status.
In this case either nothing will be printed or "status: unknown".
