        !            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.

        !            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.

        !            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.

        !            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

        !            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.
