The .Nm is found on the Sun 10/100 Mbit Ethernet boards (Sun part number SUNW,501-2655). .Pp The .Nm is not capable of link autonegotiation, so a media type must be specified with .Xr ifconfig 8 . The supported media types are: .Bl -tag -width xxxxxxxxxx -offset indent .It Cm media No 100baseTX Cm mediaopt No half-duplex Use 100Mbps, half duplex .It Cm media No 10baseT Cm mediaopt No half-duplex Use 10Mbps, half duplex .El .Sh SEE ALSO .Xr arp 4 , .Xr ifmedia 4 , .Xr inet 4 , .Xr intro 4 , .Xr netintro 4 , .Xr qec 4 , .Xr sbus 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Sh HISTORY The .Nm driver first appeared in .Ox 3.0 .
