UDBP(4)			 BSD Kernel Interfaces Manual		       UDBP(4)

NAME
     udbp -- USB Double	Bulk Pipe driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following line in your
     kernel configuration file:

	   device udbp

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   udbp_load="YES"

DESCRIPTION
     The udbp driver provides support for host-to-host cables that contain at
     least two bulk pipes (one for each	direction), for	example	the EzLink ca-
     ble and the NetChip 1080 chip.

     It	requires netgraph(4) to	be available.  This can	be done	either by
     adding options NETGRAPH to	your kernel configuration file,	or alterna-
     tively loading netgraph(4)	as a module, either from /boot/loader.conf or
     from the command line, before the udbp module.

EXAMPLES
	   options NETGRAPH
	   device udbp

     Add the udbp driver to the	kernel.

	   kldload netgraph
	   kldload udbp

     Load the netgraph(4) module and then the udbp driver.

	   ngctl mkpeer	udbp0: iface data inet
	   ifconfig ng0	10.0.0.1 10.0.0.2

     Create a new network interface node and connect its inet hook to the data
     hook of the udbp node.  ifconfig(8) configures the	resulting network in-
     terface 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.
