de - DEC DEUNA 10 Mb/s Ethernet interface
NDE de_controllers # DEUNA
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.
The de interface employs the address resolution protocol described in arp(4P) to dynami-
cally map between Internet and Ethernet addresses on the local network.
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 SIOCSIF-
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 transmit-
ting 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: can't handle af%d. The interface was handed a message with addresses formatted in
an unsuitable address family; the packet was dropped.
de%d: buffer unavailable. The interface received more packets than it had buffers allo-
cated to receive them.
de%d: address change failed, csr0=%b csr1=%b. The interface was unable to reprogram its
physical ethernet address. This may happen with very early models of the interface. This
facility is used only when the controller is not the first network interface configured
The following messages indicate a probable hardware error performing the indicated opera-
tion 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.
