Regarding carl9170 wifi linux driver

Regarding carl9170 wifi linux driver

[Prashant Badsheshi]

Hi,

We are planning to use the below wifi dongle as station and AP.

https://www.thinkpenguin.com/gnu-linux/penguin-wireless-n-usb-adapter



We got the linux driver from the below path

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git



We found the driver source in drivers/net/wireless/ath/carl9170.



Our Question:

Is the carl9170 driver present in the above folder is a complete open
source driver?

Or is it not complete driver and is there any NON-GPL code that is not
provided as an open source?

Please clarify it. Your immediate response would be really appreciated.



Also it would be great if there is any design document or programmer’s
document for the above mentioned Wifi dongle chipset available.



Regards,

Prashant

EVERYTHING in the Linux kernel in any one of the official trees, including 
wireless-testing, is licensed under GPL.

The chip AR9170 is getting on a bit. But ok.

A (compiled) firmware is available from:
http://wireless.kernel.org/en/users/Drivers/carl9170

and the firmware source from:
https://github.com/chunkeey/carl9170fw

The driver and firmware are GPLv2 code.

Well, the original vendor firmware:
http://linuxwireless.org/en/users/Drivers/ar9170.fw
and the original vendor driver:
[ The most up-to-date version is available from the
kernel git. Just revert "staging: remove the Atheros otus vendor driver"
cff55f50b882b197a52c4cf0108a43c615d1fdba ] 

For more [HW design docs, register file, etc...] you need to talk to
Qualcomm Atheros. But if there's an open issue/specific question I
would be glad to help as well [or forward the request].
