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

                     79: .SH BUGS
                     80: The encapsulation of trailer packets in the 4.2BSD version of this driver
                     81: was incorrect (the packet type was in VAX byte order).
                     82: As a result, the trailer encapsulation in this version is not compatible
                     83: with the 4.2BSD VAX version.
