NAME
le —
HP AMD 7990 LANCE Ethernet
interface
SYNOPSIS
device le0 at scode?
DESCRIPTION
Thele 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.
