LE(4)                 OpenBSD Programmer's Manual (HP300)                LE(4)

NAME
     le - HP AMD 7990 LANCE Ethernet interface

SYNOPSIS
     le* at dio? scode ?

DESCRIPTION
     The le interface provides access to a 10 Mb/s Ethernet network via the
     AMD 7990 LANCE Ethernet chip set.

     Each of the host's network addresses is specified at boot time with an
     SIOCSIFADDR ioctl. The le interface employs the address resolution proto-
     col described in arp(4) to dynamically map between Internet and Ethernet
     addresses on the local network.

     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 HP page size.  The use of trailers is negotiated with ARP. This
     negotiation may be disabled, on a per-interface basis, by setting the
     IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.

DIAGNOSTICS
     le%d: hardware address %s.  This is a normal autoconfiguration message
     noting the 6 byte physical ethernet address of the adapter.

     de%d: can't handle af%d.  The interface was handed a message with ad-
     dresses formatted in an unsuitable address family; the packet was
     dropped.

     The following message indicates a possible hardware error performing the
     indicated operation during autoconfiguration or initialization.

     le%d: init timeout, stat = 0x%x.  The hardware did not respond to an ini-
     tialize command during reset.  The reset procedure continues anyway.
