According to http://omappedia.org/wiki/Mac80211_based_open_source_architect 
ure#To_enable_WLAN_on_the_Panda_Bo ard_Linux_Kernel the "nl80211 testmode 
command" are needed for the iw tool.

My understanding is following: The wl12xx driver needs a NVS file suitable for 
the specific hardware design. If we can use the file from 
git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git then all is 
fine. Otherwise we have to generate the NVS file via the calibration process.
