     vv — Proteon proNET 10 Megabit ring

     device vv0 at uba0 csr 0161000 vector vvrint vvxint

     The vv interface provides access to a 10 Mb/s Proteon proNET ring net‐

     The network address of the interface must be specified with an an
     SIOCSIFADDR ioctl(2) before data can be transmitted or received.  It is
     only permissible to change the network address while the interface is
     marked “down”.

     The host's hardware address is discovered by putting the interface in
     digital loopback mode (not joining the ring) and sending a broadcast
     packet from which the hardware address is extracted.

     Transmit timeouts are detected through use of a watchdog routine.	Lost
     input interrupts are checked for when packets are sent out.

     If the installation is running CTL boards which use the old broadcast
     address of ‘0’ instead of the new address of ‘0xff’, the define
     OLD_BROADCAST should be specified in the driver.

     The driver can use “trailer” encapsulation to minimize copying data on
     input and output.	This may be disabled, on a per-interface basis, by
     setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.

     vv%d: host %d.  The software announces the host address discovered during

     vv%d: can't initialize.  The software was unable to discover the address
     of this interface, so it deemed "dead" will not be enabled.

     vv%d: error vvocsr=%b.  The hardware indicated an error on the previous

     vv%d: output timeout.  The token timer has fired and the token will be

     vv%d: error vvicsr=%b.  The hardware indicated an error in reading a
     packet off the ring.

     en%d: can't handle af%d.  The interface was handed a message with
     addresses formatted in an unsuitable address family; the packet was

     vv%d: vs_olen=%d.	The ring output routine has been handed a message with
     a preposterous length.  This results in an immediate panic: vs_olen.

     netintro(4), inet(4)

     The vv driver appeared in 4.2BSD.

     The encapsulation of trailer packets in the 4.2BSD version of this driver
     was incorrect (the packet type was in VAX byte order).  As a result, the
     trailer encapsulation in this version is not compatible with the 4.2BSD
     VAX version.
