    I am seeing the same thing:

    team2# netstat -inr
    Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
    dc0 1500 <Link#1> 00:00:e8:89:b9:66 1205836 0 899804 171173 2909941

    team2# ifconfig dc0
    dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
            inet 172.22.2.12 netmask 0xfffffff0 broadcast 172.22.2.15
            ether 00:00:e8:89:b9:66
            media: Ethernet autoselect (100baseTX <full-duplex>)
            status: active

    Collisions shouldn't happen on a full-duplex link?
