    ath10k: add spectral scan feature · 855aed12
    Simon Wunderlich authored
    Adds the spectral scan feature for ath10k. The spectral scan is triggered by
    configuring a mode through a debugfs control file. Samples can be gathered via
    another relay debugfs file.
    
    Essentially, to try it out:
    
    ip link set dev wlan0 up
    echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
    echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
    iw dev wlan0 scan
    echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
    cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples
    
    This feature is still experimental. Based on the original RFC patch of
    Sven Eckelmann.
