.Sh NAME
.Nm le
.Nd AMD LANCE Ethernet interface
.Sh SYNOPSIS
.Cd "le0 at mainbus0"
.Sh DESCRIPTION
The
.Nm le
interface provides access to a 10 Mb/s Ethernet network via the
.Tn AMD
7990
.Tn LANCE
Ethernet chip set.
.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
The use of ``trailer'' encapsulation to minimize copying data on
input and output is supported by the interface but offers no advantage
due to the large
.Tn HP
page size.
The use of trailers is negotiated with
.Tn ARP .
This negotiation may be disabled, on a per-interface basis,
by setting the
.Dv IFF_NOTRAILERS
flag with an
.Dv SIOCSIFFLAGS
.Xr ioctl 2 .
