                     11: .SH SYNOPSIS
                     12: .B "device de0 at uba0 csr 174510 vector deintr"
                     13: .SH DESCRIPTION
                     14: The
                     15: .I de
                     16: interface provides access to a 10 Mb/s Ethernet network through
                     17: a Digital Equipment UNIBUS Network Adapter (DEUNA).
                     18: .PP
                     19: Each of the host's network addresses
                     20: is specified at boot time with an SIOCSIFADDR
                     21: ioctl.  The
                     22: .I de
                     23: interface employs the address resolution protocol described in
                     24: .IR arp (4P)
                     25: to dynamically map between Internet and Ethernet addresses on the local
                     26: network.
                     27: .PP
                     28: The interface normally tries to use a ``trailer'' encapsulation
                     29: to minimize copying data on input and output.
                     30: The use of trailers is negotiated with ARP.
                     31: This negotiation may be disabled, on a per-interface basis,
                     32: by setting the IFF_NOTRAILERS
                     33: flag with an SIOCSIFFLAGS ioctl.
                     34: .SH DIAGNOSTICS
                     35: \fBde%d: hardware address %s\fP.
                     36: This is a normal autoconfiguration message noting the 6 byte physical
                     37: ethernet address of the adapter.
                     38: .PP
                     39: \fBde%d: oerror, flags=%b tdrerr=%b (len=%d)\fP.
                     40: The hardware indicated an error
                     41: in transmitting a packet to the cable.
                     42: The status and error flags are reported.
                     43: .PP

                     45: The hardware indicated an error
                     46: in reading a packet from the cable.
                     47: The status and error flags are reported.
                     48: .PP
                     49: \fBde%d: can't handle af%d\fP.  The interface was handed
                     50: a message with addresses formatted in an unsuitable address
                     51: family; the packet was dropped.
                     52: .PP
                     53: \fBde%d: buffer unavailable\fP.  The interface received more packets
                     54: than it had buffers allocated to receive them.
                     55: .PP
                     56: \fBde%d: address change failed, csr0=%b csr1=%b\fP.
                     57: The interface was unable to reprogram
                     58: its physical ethernet address.
                     59: This may happen with very early models of the interface.
                     60: This facility is used only when
                     61: the controller is not the first network interface configured for XNS.
                     62: .PP
                     63: The following messages indicate a probable hardware error performing
                     64: the indicated operation during autoconfiguration or initialization.
                     65: The two control and status registers
                     66: should indicate the nature of the failure.
                     67: See the hardware manual for details.
                     68: .PP
