wl0084a / wl1271 understanding

[Raffaele Recalcati]

I'm an embedded developer and I really want opensource development for
wireless, to be sure to maintain it in many kernel versions I will
have.
I'm not an wifi expert and so I can have done some mistakes here below.

wl1271
=============
At the end of
http://processors.wiki.ti.com/index.php/ARM_Processor_Open_Source_Wireless_Connectivity
http://www.openlink.org/software/linux-kernel#lk
It seems the same as what I can find in drivers/net/wireless/wl12xx
kernel directory.

wl0084a
=============
grep -rin wl008 drivers
give no result on kernel 3.2-rc6.
What is the normal approach to take in account?
I have to immediately change the usb wifi dongle due to the lacking of
information to develop e proper driver or maybe
there is some possibility?
Here I can find Logilink drivers
http://www.logilink.eu/content/support/download.htm?seticlanguage=en
They confirm support for LINUX (kernel 2.6.18 ~ 2.6.33)
Looking into drivers files ... yes , they are proprietary.

Thanks for any help,
Raffaele

Yes, we have full support for the wl1271 chip in the mainline kernel.
We are working actively on maintaining and improving it directly
upstream.  TI makes official releases to the customers which are based
on the upstream kernel.

Join us on IRC @Freenode #wl12xx to talk more about it if you like.

Some of the Logilink devices have Realtek chips. If this is a USB device, please 
post the output of 'lsusb'. If it is PCI, post the output of 'lspci -nnv' - we 
only need the part that describes the wireless device.

If that device is Rev 1, it uses driver r8192e_pci. If it is Rev 10, then it 
uses rtl8192ce. Both drivers are in the kernel since 2.6.38, and should just 
work if your kernel is new enough.
