88w8335 [Libertas] 802.11b/g

[Luis R. Rodriguez]

Someone gave an old Marvell card, it seems to be libertas:

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

vendor:device -- 11ab:1faa

libertas_cs isn't picking up though. I found a net80211 linux based
driver which does have it though. I haven't touched this hardware
until now. How different are they? Anyone already working on the
net80211 driver port to mac80211?

The topdog needs a port too but that's different.

libertas wasn't written for 8335 chips. The whole of libertas, 
including "if_cs.c", is currently only for 8385 chips.

I saw a driver for 8335 chips at 
http://david.woodhou.se/mrv.tar.gz. Do you refer to the same 
one?

As this driver was originally written for mac80211, I'd prefer it 
over a driver/net/wireless/libertas based driver, e.g. via an 
hyptothetical "if_pci.c". Maybe you need to dust of a bit of 
bitrot. Maybe it's even worth pushing this driver into shape and 
submitting it to Linville for kernel adoption.

There's also mrv8k which apparently Ubuntu is shipping (although it
doesn't work).  Google around for it.  OpenSolaris and OpenBSD have the
'malo(4)' driver for this part, including the 8310 and 8335 chips.

I also picked up a cardbus card with an 8300 or 8335 in it this past
week.  (TrendNET branded).  I cleaned it up for There are problems with
the mrv8k driver where it appears to panic in the interrupt handler.

The 8335 is a _softmac_ part and therefore won't work (ever) with the
current libertas driver, which is a fullmac part.  The best solution is
to write a new mac80211 driver for the 8335 parts.

The firmware situation is a lot like the broadcom parts where you need a
firmware cutter to pull firmware out of the Windows .sys driver file.
Two firmware are required, the boot firmware and the main firmware.
