wireless chipsets not supported by current wireless tree

wireless chipsets not supported by current wireless tree

[Stephen Hemminger]

Anyone keep a list of the important chips not supported by the current
wireless tree? I know about Atheros, and the upcoming Marvell stuff but
what about the others.

Is there a chance of or anyone already working on Marvell (non-OLPC) support,
e.g., for one of these?

00:09.0 Ethernet controller: Marvell Technology Group Ltd. 88w8335 [Libertas] 
             802.11b/g Wireless (rev 03)

Yes. (not me though I do own a PCI marvell card)

Yes, there is someone working there. A bunch of my patches to 
shape the OLPC driver in a way libertas_lib.ko, libertas_usb.ko, 
libertas_cs.ko got already applied. I made some experiments with 
firmware download, David Anders wrote a fwcutter and so on.

I once created a project 
http://projects.linuxtogo.org/projects/marvell8385/, but most of 
the discussion happend now in the OLPC Marvell mailing list.

Nothing works yet, and I got (and will get) distracted because my 
company switched to SAP Business One and I'm mostly busy 
extracting data out of our old system and putting that into 
SAPB1 :-(  Maybe I have again time this week.

That chip has some significant differences to the 838x line that the
OLPC and others are using.  I'm not sure we can support that chipset in
the same driver, unless its firmware interface is quite similar.

small note: I'd rather have the bus-independent part be called
"libertas.ko" rather than _lib.

The list and channel aren't supposed to be OLPC specific, really, hence
the generic "libertas-dev" name and such.  Since you're around, it's no
longer only OLPC people happening to work on the driver, and that's the
way it should be.

Great.  Let's make the driver Not Suck :)

I'm not aware of such list.  I think it could be placed on
http://linuxwireless.org/

Just off the top of my head:

No known drivers:

Airgo
Atheros draft-802.11n PCI
Atheros USB

Vendor drivers in unusable condition (importance is arguable):

Hermes 2/2.5
Am1771

Drivers outside the tree:

Intel ipw3945
rtl818x PCI
Atmel USB

Drivers in the tree but currently unusable:

rt61

This list may be helpful, but most chipsets listed there are obsolete:
