Marvell 88w8335 [Libertas]

[Markus Becker]

Dear all,

I am trying to use the WLAN part of an Option Fusion+ UMTS and WLAN card. 
UMTS is working fine, WLAN works OK with ndiswrapper. Seen the emails on 
infradead and linuxwireless from 2007 and beginning of March, I was trying 
to get it natively supported.

I modified the mac80211 port of mrv8k from 
http://david.woodhou.se/mrv.tar.gz so that it compiles against 2.6.24 
Debian kernel.

It is available here:
https://www.comnets.uni-bremen.de/~mab/mrv8k/mrv8kng-mab.tgz

The firmware I am using is extracted from Mrvw123.sys from the CD of the 
UMTS/WLAN card using mrv8k_extract_fw.

The module loads (does not bail out in the interrupt handler) and 
creates the devices:

Mar 19 09:55:07 shelbyville kernel: d80211 Marvell Libertas PCI driver
Mar 19 09:55:07 shelbyville kernel: Andrea Merello <andreamrl *at* tiscali.it>
Mar 19 09:55:20 shelbyville kernel: pccard: CardBus card inserted into slot 0
Mar 19 09:55:20 shelbyville kernel: PCI: Enabling device 0000:16:00.0 (0000 -> 0002)
Mar 19 09:55:20 shelbyville kernel: ACPI: PCI Interrupt 0000:16:00.0[A] -> GSI 16 (level, low) -> IRQ 16
Mar 19 09:55:20 shelbyville kernel: PCI: Setting latency timer of device 0000:16:00.0 to 64
Mar 19 09:55:20 shelbyville kernel: Bootstrap loaded OK, jumping in..
Mar 19 09:55:22 shelbyville kernel: Firmware load successfully
Mar 19 09:55:22 shelbyville kernel: Card mac address is xx:xx:xx:xx:xx:xx
Mar 19 09:55:22 shelbyville kernel: Fw V 3020007, Hw V 3, Anennas: 2, Region code 48
Mar 19 09:55:22 shelbyville kernel: phy7: Selected rate control algorithm 'simple'
[Snipped out nozomi UMTS driver.]

It is not yet fully working, however. The card does not seem to react on 
the scanning/set_channel commands:

Mar 19 09:55:48 shelbyville kernel: Command timeout
Mar 19 09:55:48 shelbyville kernel: Could not set channel
Mar 19 09:55:48 shelbyville kernel: Failed to set channel
Mar 19 09:55:48 shelbyville kernel: wlan1: failed to set channel 2 (2417 MHz) for scan
Mar 19 09:55:50 shelbyville kernel: Command timeout
Mar 19 09:55:50 shelbyville kernel: Could not set channel
Mar 19 09:55:50 shelbyville kernel: Failed to set channel
Mar 19 09:55:50 shelbyville kernel: wlan1: failed to set channel 3 (2422 MHz) for scan
[...]

If someone is interested in helping (I am not very familiar with linux 
wireless development), please contact me.

Best regards,
Markus
