# NAME

`de` — DEC DEUNA/DELUA 10 Mb/s Ethernet interface

# SYNOPSIS

`de0 at uba? csr 174510`

# DESCRIPTION

The `de` interface provides access to a 10 Mb/s Ethernet network through a Digital Equipment UNIBUS Network Adapter (DEUNA).

Each of the host's network addresses is specified at boot time with an `SIOCSIFADDR` ioctl(2). The `de` interface employs the address resolution protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.

# 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 (len=%d).
  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.

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.
