Problem with ethernet card; can somebody interpret this output....?

For whatever reason, my ethernet card isn't functioning.

Code: 
lo0: link state changed to UP
Starting Network: lo0 em0.
lo0: flags=1008049<UP,LOOPBACK,RUNNING,MULTICAST,LOWER_UP> metric 0 mtu 16384
        options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2
        groups: lo
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4e524bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,LRO,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6,HWSTATS,MEXTPG>
        ether b8:ca:3a:8d:e6:58
        inet6 fe80::baca:3aff:fe8d:e658%em0 prefixlen 64 scopeid 0x1
        media: Ethernet autoselect
        status: no carrier
        nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>

I'm clueless, and I'd be much obliged to anyone who can infer anything at all from this. Please excuse me if this post is off-topic....?

It's not connected, in other words, there's no network cable plugged in. It's not detecting the carrier signal. Could be a bad cable, bad switch port or broken network card. Cable is the easiest to test, try another. Check the switch port by plugging it in a different port. Broken card is more difficult, but if the cable is good, and the switch port is good, then it's possible the card is broken.
 
Was it working before?

If it was, before what (what did you change?)

Look in /var/log/messages to see if anything in there. What's in /etc/rc.conf - are there any ifconfig_<something> lines?

This was the same process of elimination that I followed: the port and cable(s) function otherwise, so I'm all but certain that the card is faulty. Thanks for substantiating this.

I don't know what to detect in the former; all messages pertaining to em0 look usual. As for rc.conf:

Code: 
ifconfig_em0="DHCP"
ifconfig_em0_ipv6="inet6 accept_rtadv"
