It's 3.15, specifically the Linaro release (linux-linaro-3.15-2014.06) however I can build any mainline kernel or backport if needed. The driver reports version 1.0 (14.66.9.p96). I believe that adapter->ext_scan is always enabled with the way the code is written, however I've confirmed it just in case. Also I meant: iw dev mlan0 scan freq 2412 ...in my previous message. > ________________________________________ > From: linux-wireless-owner@xxxxxxxxxxxxxxx [linux-wireless-owner@xxxxxxxxxxxxxxx] On Behalf Of Andrey Yurovsky [yurovsky@xxxxxxxxx] > Sent: Tuesday, August 05, 2014 12:41 AM > To: linux-wireless@xxxxxxxxxxxxxxx > Subject: scanning only returns results on specified channels (Marvell mwifiex driver) > > I am not seeing scan results on my test setup with a Marvell 88W8787 > (mwifiex driver) connected over SDIO to an ARM926.
