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

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

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

     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 asso-
                    ciating 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 communica-
     tion, 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).

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


     These firmware files are not free because Marvell refuses to grant dis-
     tribution 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

     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

     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

           nwid mynwid
           wpakey mywpakey

     arp(4), cardbus(4), ifmedia(4), intro(4), netintro(4), pci(4),
     hostname.if(5), hostapd(8), ifconfig(8)

     The malo driver first appeared in OpenBSD 4.1.

     The malo driver was written by Claudio Jeker and Marcus Glocker.

     WPA encryption is not supported for PCMCIA devices.
