malo driver provides support for
Marvell Libertas 88W8335/88W8310/88W8385 based PCI/CardBus/PCMCIA network
adapters. The second generation 88W8335/88W8310 chipsets support
These are the modes the
malo driver can
- 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.
malo driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA1 and WPA2).
WPA2 is the current encryption standard for wireless networks. It is
strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses. WPA1
is disabled by default and may be enabled using the option
wpa1,wpa2". For standard WPA networks which use
pre-shared keys (PSK), keys are configured using the
wpakey" option. WPA-Enterprise networks
require use of the wpa_supplicant package. The
driver relies on the software 802.11 stack for both encryption and
decryption of data frames.
malo driver can be configured at
ifconfig(8) or on boot with
The driver needs a set of firmware files which are loaded when an interface is brought up:
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(8).
The following cards are among those supported by the
|I-O DATA WN-G54/CF||88W8385||PCMCIA||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 DHCP:
join mynwid wpakey mywpakey inet autoconf
arp(4), cardbus(4), ifmedia(4), intro(4), netintro(4), pci(4), hostname.if(5), ifconfig(8)

WPA encryption is not supported for PCMCIA devices.
This driver does not support powersave mode.
