NTB(4)							   BSD Kernel Interfaces Manual 						    NTB(4)

NAME

     ntb, ntb_hw, if_ntb -- Intel(R) Non-Transparent Bridge driver

SYNOPSIS

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

	   device ntb_hw
	   device if_ntb

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

	   if_ntb_load="YES"

DESCRIPTION

     The ntb driver provides support for the Non-Transparent Bridge (NTB) in the Intel S1200, Xeon E3 and Xeon E5 processor families.

     The NTB allows you to connect two computer systems using a PCI-e link if they have the correct equipment and connectors.

CONFIGURATION

     The NTB memory windows need to be configured by the BIOS.	If your BIOS allows you to set their size, you should set the size of both memory
     windows to 1 MiB.	This needs to be done on both systems.

     Each system needs to have a different IP address assigned.  The MAC address is randomly generated.  Also for maximum performance, the MTU
     should be set to 16 kiB.  This can be done by adding the line below to rc.conf(5):

	   ifconfig_ntb0="inet 192.168.1.10 netmask 255.255.255.0 mtu 16384"

     And on the second system :

	   ifconfig_ntb0="inet 192.168.1.11 netmask 255.255.255.0 mtu 16384"

     If you are using the UDP protocol, you may want to increase the net.inet.udp.maxdgram sysctl(8) variable.

SEE ALSO

     rc.conf(5), sysctl(8)

AUTHORS

     The ntb driver was developed by Intel and originally written by Carl Delsey <carl@FreeBSD.org>.

BUGS

     If the driver is unloaded, it cannot be reloaded without a system reboot.

     The network support is limited.  It isn't fully configurable yet.	It also isn't integrated into netgraph(4) or bpf(4).

     NTB to Root Port mode is not yet supported.

     There is no way to protect your system from malicious behavior on the other system once the link is brought up.  Anyone with root or kernel
     access on the other system can read or write to any location on your system.  In other words, only connect two systems that completely trust
     each other.

MALO(4) 						   BSD Kernel Interfaces Manual 						   MALO(4)

NAME

     malo -- Marvell Libertas IEEE 802.11b/g wireless network driver

SYNOPSIS

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

	   device malo
	   device pci
	   device wlan
	   device firmware

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

	   if_malo_load="YES"

DESCRIPTION

     The malo driver provides support for Marvell Libertas 88W8335 based PCI and Cardbus network adapters.  malo supports station and monitor mode
     operation.  Only one virtual interface may be configured at any time.  For more information on configuring this device, see ifconfig(8).

     This driver requires the malofw firmware kernel module be installed before it will work.  The firmware files are not publicly available.  A
     port of the firmware can be found at:

	   http://weongyo.org/project/malo/malo-firmware-1.4.tar.gz

     The firmware kernel module can be installed by extracting the archive and running 'make install clean' in the malo-firmware-1.4 directory.

     To load the malofw firmware kernel module at boot time, place the following line in loader.conf(5):

	   malofw_load="YES"

HARDWARE

     The following cards are among those supported by the malo driver:

     Card		Chip	   Bus	  Standard
     Netgear WG311v3	88W8335    PCI	  b/g
     Tenda TWL542P	88W8335    PCI	  b/g
     U-Khan UW-2054i	88W8335    PCI	  b/g

EXAMPLES

     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wlan create wlandev malo0 inet 192.168.0.20 
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create wlandev malo0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create wlandev malo0 ssid my_net 
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

HISTORY

     The malo device driver first appeared in FreeBSD 7.1.
