.Dd February 5, 2019 .Dt VV 4 vax .Os .Sh NAME .Nm vv .Nd Proteon proNET 10 Megabit ring network .Sh SYNOPSIS .Cd "vv0 at uba0 csr 0161000 vector vvrint vvxint" .Sh DESCRIPTION NOTE: This driver has not been ported from x 4.4 yet.
p The .Nm vv interface provides access to a 10 Mb/s Proteon .Tn proNET ring network.
p The network address of the interface must be specified with an .Dv SIOCSIFADDR .Xr ioctl 2 before data can be transmitted or received. It is only permissible to change the network address while the interface is marked .Dq down .
p 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.
p Transmit timeouts are detected through use of a watchdog routine. Lost input interrupts are checked for when packets are sent out.
p If the installation is running .Tn CTL boards which use the old broadcast address of .Ql 0 instead of the new address of .Ql 0xff , the define .Dv OLD_BROADCAST should be specified in the driver. .Sh DIAGNOSTICS l -diag t vv%d: host %d. The software announces the host address discovered during autoconfiguration. t vv%d: can't initialize. The software was unable to discover the address of this interface, so it deemed "dead" will not be enabled. t vv%d: error vvocsr=%b. The hardware indicated an error on the previous transmission. t vv%d: output timeout. The token timer has fired and the token will be recreated. t vv%d: error vvicsr=%b. The hardware indicated an error in reading a packet off the ring. t vv%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped. t vv%d: vs_olen=%d. The ring output routine has been handed a message with a preposterous length. This results in an immediate .Em panic: vs_olen . .El .Sh SEE ALSO .Xr inet 4 , .Xr netintro 4 .Sh HISTORY The .Nm driver appeared in x 4.2 .
