.Sh DESCRIPTION
The
.Nm
driver provides access to the on-board AMD 7990/LANCE interface,
as well as the VME Interphase 3207 Hawk Ethernet boards.
This in turn provides an interface to the
.Tn Ethernet
network.
.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
.Tn Ethernet
addresses on the local network.
.\" XXX this section needs a rework -- miod
.\" .Sh HARDWARE CONFIGURATION
.\" The card's base address
.\" .Po
.\" matching the
.\" .Em addr
.\" locator on the configuration line
.\" .Pc
.\" is defined through three sets of DIP switches,
.\" .Dq SW1
.\" and
.\" .Dq SW2 ,
.\" located in the middle of the board, near the space between the two
.\" VME connectors, and
.\" .Dq SW3 ,
.\" closer to the AM7990DC chip at the bottom edge.
.\" .Pp
.\" The only supported configurations are:
.\" .Bl -column "xxxxxxxx" "xxxxxxxx" "xxxxxxxx" "0xffffffff"
.\" .It Li SW1 Ta SW2 Ta SW3 Ta Address
