                     11: .SH SYNOPSIS
                     12: .B "device vv0 at uba0 csr 0161000 vector vvrint vvxint"
                     13: .SH DESCRIPTION
                     14: The
                     15: .I vv
                     16: interface provides access to a 10 Mb/s Proteon proNET ring network.
                     17: .PP
                     18: The network address of the interface must be specified with an
                     19: an SIOCSIFADDR ioctl before data can be transmitted or received.
                     20: It is only permissible to change the network address while the
                     21: interface is marked "down".
                     22: .PP
                     23: The host's hardware address is discovered by putting the interface in
                     24: digital loopback mode (not joining the ring) and sending a broadcast
                     25: packet from which the hardware address is extracted.
                     26: .PP
                     27: Transmit timeouts are detected through use of a watchdog routine.
                     28: Lost input interrupts are checked for when packets are sent out.
                     29: .PP
                     30: If the installation is running CTL boards which use the old broadcast
                     31: address of 0 instead of the new address of 0xff, the define OLD_BROADCAST
                     32: should be specified in the driver.
                     33: .PP
                     34: The driver can use ``trailer'' encapsulation to minimize copying
                     35: data on input and output.
                     36: This may be disabled, on a per-interface basis,
                     37: by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
                     38: .SH DIAGNOSTICS
                     39: .PP
                     40: \fBvv%d: host %d\fP.  The software announces the host
                     41: address discovered during autoconfiguration.
                     42: .PP
                     43: \fBvv%d: can't initialize\fP. The software was unable to
                     44: discover the address of this interface, so it deemed
                     45: "dead" will not be enabled.
                     46: .PP
                     47: \fBvv%d: error vvocsr=%b\fP.  The hardware indicated an error on
                     48: the previous transmission.
                     49: .PP
                     50: \fBvv%d: output timeout\fP.  The token timer has fired and the
                     51: token will be recreated.
                     52: .PP
                     53: \fBvv%d: error vvicsr=%b\fP.  The hardware indicated an error
                     54: in reading a packet off the ring.
                     55: .PP
                     56: \fBen%d: can't handle af%d\fP.  The interface was handed
                     57: a message with addresses formatted in an unsuitable address
                     58: family; the packet was dropped.
                     59: .PP
                     60: \fBvv%d: vs_olen=%d\fP.  The ring output routine has been
                     61: handed a message with a preposterous length.  This results in
                     62: an immediate 
                     63: .IR "panic: vs_olen" .

                     66: .SH BUGS
                     67: The encapsulation of trailer packets in the 4.2BSD version of this driver
                     68: was incorrect (the packet type was in VAX byte order).
                     69: As a result, the trailer encapsulation in this version is not compatible
                     70: with the 4.2BSD VAX version.
