Problems using the libertas

[Kalkere, Giridhara(IE10)]

Dan,

I understand the 2.6.31 is older kernel version. But our product is built with this version and the we are using the imx35 platform. So Freescale is not supporting any more.

Is there any one back ported the libertas driver to 2.6.31 kernel version.

Please help me to back port the latest libertas driver to 2.6.31 kernel version.

Thanks and regards,
Giri

Well, the 2.6.31 kernel is almost 4 years old already, so yeah, there have been a lot of fixes to the driver since then.  If you're at all able to use a 3.x kernel, preferably 3.5 or 3.6, that would be great.
You could try backporting the driver from the latest kernels to 2.6.31.
