                     30: .SH DESCRIPTION
                     31: The
                     32: .I le
                     33: interface provides access to a 10 Mb/s Ethernet network via the
                     34: AMD 7990 LANCE Ethernet chip set.
                     35: .PP
                     36: Each of the host's network addresses
                     37: is specified at boot time with an SIOCSIFADDR
                     38: ioctl.  The
                     39: .I de
                     40: interface employs the address resolution protocol described in
                     41: .IR arp (4P)
                     42: to dynamically map between Internet and Ethernet addresses on the local
                     43: network.
                     44: .PP
                     45: The use of ``trailer'' encapsulation to minimize copying data on
                     46: input and output is supported by the interface but offers no advantage
                     47: due to the large HP page size.
                     48: The use of trailers is negotiated with ARP.
                     49: This negotiation may be disabled, on a per-interface basis,
                     50: by setting the IFF_NOTRAILERS
                     51: flag with an SIOCSIFFLAGS ioctl.

                     53: \fBle%d: hardware address %s\fP.

                     65: The hardware did not respond to an initialize command during reset.
