                     11: .SH SYNOPSIS
                     12: .B "device ex0 at uba0 csr 164000 vector excdint"
                     13: .SH DESCRIPTION
                     14: The
                     15: .I ex
                     16: interface provides access to a 10 Mb/s Ethernet network through
                     17: an Excelan controller used as a link-layer interface.
                     18: .PP
                     19: Each of the host's network addresses
                     20: is specified at boot time with an SIOCSIFADDR
                     21: ioctl.  The
                     22: .I ex
                     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: \fBex%d: HW %c.%c, NX %c.%c, hardware address %s\fP.
                     36: This provides firmware revisions levels, and is expected during
                     37: autoconfiguration.

                     39: \fBex%d: can't initialize\fP.
                     40: There was a failure in allocating unibus resources for the device.
                     41: .PP
                     42: \fBex%d: configuration failed; cc = %x\fP.
                     43: The hardware indicated an error when trying to initalize itself.
                     44: The error code returned is described at length in the device
                     45: Reference Manual.
                     46: .PP
                     47: \fBex%d: receive error %b\fP.  The hardware indicated an error
                     48: in reading a packet from the cable.
                     49: Specific Error bits are provided

                     51: \fBex%d: transmit error %b\fP.  The hardware indicated an error
                     52: in transmitting a packet to the cable or an illegally sized packet.
                     53: Specific Error bits are provided
                     54: .PP
                     55: \fBex%d: can't handle af%d\fP.  The interface was handed
                     56: a message with addresses formatted in an unsuitable address
                     57: family; the packet was dropped.
