DE(4) OpenBSD Programmer's Manual (VAX) DE(4)NAME
de - DEC DEUNA/DELUA Ethernet device
SYNOPSIS
de0 at uba? csr 0174510
DESCRIPTION
The de interface provides access to a 10 Mb/s Ethernet network through a
Digital Equipment UNIBUS Network Adapter (DEUNA).
The interface normally tries to use a ``trailer'' encapsulation to
minimize copying data on input and output. 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(2).
DIAGNOSTICS
de%d: hardware address %s. This is a normal autoconfiguration message
noting the 6 byte physical Ethernet address of the adapter.
de%d: oerror, flags=%b tdrerr=%b. The hardware indicated an error in
transmitting a packet to the cable. The status and error flags are
reported.
de%d: ierror, flags=%b lenerr=%b (len=%d). The hardware indicated an
error in reading a packet from the cable. The status and error flags are
reported.
de%d: buffer unavailable. The interface received more packets than it
had buffers allocated to receive them.
The following messages indicate a probable hardware error performing the
indicated operation during autoconfiguration or initialization. The two
control and status registers should indicate the nature of the failure.
See the hardware manual for details.
de%d: reset failed, csr0=%b csr1=%b.
de%d: ppcb failed, csr0=%b csr1=%b.
de%d: read addr failed, csr0=%b csr1=%b.
de%d: wtring failed, csr0=%b csr1=%b.
de%d: wtmode failed, csr0=%b csr1=%b.
