+.Sh SYNOPSIS

+.Sh DESCRIPTION
+The
+.Nm
+interface provides access to the 10Mb/s, 100Mb/s and 1Gb/s Ethernet networks.
+.\" ... via the FOO or the BAR chipsets.
+The
+.Nm
+is found on the
+.Tn Sun
+GEM and ERI 10/100 boards, as well as the
+.Tn Apple
+internal GMAC ethernet.
+.Pp
+Each of the host's network addresses
+is specified at boot time with an
+.Dv SIOCSIFADDR
+.Xr ioctl 2 .
+The
+.Nm
+interface employs the address resolution protocol described in
+.Xr arp 4
+to dynamically map between Internet and Ethernet addresses on the local
+network.
+.Pp
+When a
+.Nm
+interface is brought up, by default, it will attempt to auto-negotiate the
+link speed and duplex.
+The speeds are tried in descending order; first in full duplex mode, then
+half duplex.
+.Pp
+The
+.Nm
+supports several media types, which are selected via the
+.Xr ifconfig 8
+command.
+The supported media types are:
+.Bl -tag -width "media autoselect" -offset indent
+.It media autoselect
+Attempt to autoselect the media type (default)
+.\" Check and correct the gigabit modes. Are both copper and fiber supported?
+.\" And in both duplex modes as well?
+.It media 1000baseTX  mediaopt full-duplex
+Use 1000baseSX on copper, full duplex
+.It media 1000baseTX Op mediaopt half-duplex
+Use 1000baseSX on copper, half duplex
+.It media 1000baseSX  mediaopt full-duplex
