LE(4)

NAME
le - HP AMD 7990 LANCE Ethernet interface

SYNOPSIS
device le0 at 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 protocol 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 addresses 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 initialize command during reset. The reset procedure continues anyway.
