fully useful when the system doesn't supply anything to configure the interface with. So remove rump_virtif_create(), that functionality is now taken care of with ifcloner.

.Sh NAME
|
|
.Nm virt
|
|
.Nd rump kernel virtual network interface
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface acts as a link between a rump kernel and a host
|
|
.Xr tap 4
|
|
interface.
|
|
Interface number <n> always corresponds with the host tap interface tap<n>.
|
|
All data sent by
|
|
.Nm
|
|
is written into
|
|
.Pa /dev/tap<n>
|
|
and all data read from
|
|
.Pa /dev/tap<n>
|
|
is passed as Ethernet input to the rump kernel.
|
|
.Pp
|
|
A
|
|
.Nm
|
|
interface can be created and destroyed in the normal fashion with
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
The host's
|
|
.Xr tap 4
|
|
interface can be further bridged with hardware interfaces to provide
|
|
full Internet access to a rump kernel.
