de - DEC DEUNA/DELUA 10 Mb/s Ethernet interface
de0 at uba? csr 0174510
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
protocol described in arp(4) to dynamically 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
with ARP. This negotiation may be disabled, on a per-interface basis, by
setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS
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
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
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
