NAME

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


SYNOPSIS

     malo* at cardbus?
     malo* at pci?
     malo* at pcmcia?


DESCRIPTION

     The malo driver provides support for Marvell Libertas
     88W8335/88W8310/88W8385 based PCI/CardBus/PCMCIA network adapters.  The
     second generation 88W8335/88W8310 chipsets support 802.11b/g.

     These are the modes the malo driver can operate in:

     BSS mode       Also known as infrastructure mode, this is used when
                    associating with an access point, through which all
                    traffic passes.  This mode is the default.

     monitor mode   In this mode the driver is able to receive packets without
                    associating with an access point.  This disables the
                    internal receive filter and enables the card to capture
                    packets from networks which it wouldn't normally have
                    access to, or to scan for access points.

     The malo driver can be configured to use Wired Equivalent Privacy (WEP)
     or Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).  WPA is the current
     encryption standard for wireless networks.  It is strongly recommended
     that WEP not be used as the sole mechanism to secure wireless
     communication, due to serious weaknesses in it.  The malo driver relies
     on the software 802.11 stack for both encryption and decryption of data
     frames.

     The malo driver can be configured at runtime with ifconfig(8) or on boot
     with hostname.if(5).


FILES

     The driver needs a set of firmware files which are loaded when an
     interface is brought up:

           /etc/firmware/malo8335-h
           /etc/firmware/malo8335-m
           /etc/firmware/malo8338
           /etc/firmware/malo8385-h
           /etc/firmware/malo8385-m

     These firmware files are not free because Marvell refuses to grant
     distribution rights.  As a result, even though OpenBSD includes the
     driver, the firmware files cannot be included and users have to download
     these files on their own.

     A prepackaged version of the firmware can be installed using
     fw_update(1).


HARDWARE

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

           Card                  Chip       Bus        Standard
           Ambicom WL54CF        88W8385    PCMCIA     b/g
           I-O DATA WN-G54/CF    88W8385    PCMCIA     b/g
           Netgear WG511v2       88W8310    CardBus    b/g
           Netgear WG311v3       88W8335    PCI        b/g
           SparkLAN WCFM-100     88W8385    PCMCIA     b/g
           Tenda TWL541C         88W8310    CardBus    b/g
           Tenda TWL542P         88W8335    PCI        b/g


EXAMPLES

     The following example scans for available networks:

           # ifconfig malo0 scan

     The following hostname.if(5) example configures malo0 to join network
     "mynwid", using WPA key "mywpakey", obtaining an IP address using DHCP:

           nwid mynwid wpakey mywpakey
           dhcp
