.Sh SYNOPSIS
|
||
|
|
.Cd "device le0 at scode?"
|
||
|
|
.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 .
|
||
|
|
The
|
||
|
|
.Xr le
|
||
|
|
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 .
|
||
|
|
.Sh DIAGNOSTICS
|
||
|
|
.Bl -diag
|
||
|
|
.It le%d: hardware address %s.
|
||
|
|
This is a normal autoconfiguration message noting the 6 byte physical
|
||
|
|
ethernet address of the adapter.
|
||
|
|
.Pp
|
||
|
|
.It 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.
|
||
|
|
.Pp
|
||
|
|
The following message indicate a possible hardware error performing
|
||
|
|
the indicated operation during autoconfiguration or initialization.
|
||
|
|
.Pp
|
||
|
|
.It le%d: init timeout, stat = 0x%x.
|
||
|
|
The hardware did not respond to an initialize command during reset.
|
||
|
|
The reset procedure continues anyway.
