Perhaps you want the "ifconfig -m _interface_" command, as in:
# ifconfig -m bge0
bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
options=1a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
capability list:
=1a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
ether 00:b0:d0:e1:92:a1
media: Ethernet autoselect (none)
status: no carrier
supported media:
media autoselect
media 1000baseTX mediaopt full-duplex
media 1000baseTX
media 100baseTX mediaopt full-duplex
media 100baseTX
media 10baseT/UTP mediaopt full-duplex
media 10baseT/UTP
media none
