It should be limited to the .\" netgraph(4) manpage only. However, that page does .\" not yet give instructions for kldload(8) for the .\" clueless. Working on it -- sheldonh It requires .Xr netgraph 4 to be avalable. This can be done either by adding .Cd "options NETGRAPH" to your kernel configuration file, or alternatively loading .Xr netgraph 4 as a module, either from .Pa /boot/loader.conf or from the command line, before the .Nm module. .Sh EXAMPLE .Dl options NETGRAPH .Dl device udbp .Pp Add the .Nm driver to the kernel. .Pp .Dl kldload netgraph .Dl kldload udbp .Pp Load the .Xr netgraph 4 module and then the .Nm driver. .Pp .Dl ngctl mkpeer udbp0: iface data inet .Dl ifconfig ng0 10.0.0.1 10.0.0.2 .Pp Create a new network interface node and connect its inet hook to the data hook of the .Nm node. .Xr ifconfig 8 configures the resulting network interface ng0 with a local IP address of 10.0.0.1 and a remote IP address of 10.0.0.2. On the remote host, the two IP addresses should of course be reversed. .Pp .Sh SEE ALSO .Xr netgraph 4 , .Xr ohci 4 , .Xr uhci 4 , .Xr usb 4 , .Xr ng_iface 8 , .Xr ngctl 8 .Sh HISTORY The .Nm driver first appeared in .Fx 5.0 . .Sh AUTHORS The .Nm driver was written by .An Doug Ambrisko Aq ambrisko@whistle.com , .An Julian Elischer Aq julian@whistle.com and .An Nick Hibma Aq n_hibma@freebsd.org . .Pp This manual page was written by .An Nick Hibma Aq n_hibma@freebsd.org .
