I also found out yesterday that the ifconfig from net-tools version 6.1-6 is
broken on my machine. The last combination of packages to work for me is
net-tools 6.1-4 and freebsd-hackedutils 5.2.1-32. With the latest packages I
get this behaviour:
$ ifconfig -a
em0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
ether 0:c:76:3f:d6:72
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
fwe0: flags=108802<BROADCAST,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
options=8<VLAN_MTU>
ether 2:0:10:37:8d:ed
ch 1 dma -1
lo0: flags=8008<LOOPBACK,MULTICAST> mtu 16384
$ ifconfig lo0
ifconfig: interface lo0 does not exist
