    cfg80211: return channel noise via survey API · 61fa713c
    Holger Schurig 提交于
    This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
    ops that a driver can implement. The goal of this command is to allow a
    drivers to report channel survey data (e.g. channel noise, channel
    occupation).
    
    For now, only the mechanism to report back channel noise has been
    implemented.
    
    In future, there will either be a survey-trigger command --- or the existing
    scan-trigger command will be enhanced. This will allow user-space to
    request survey for arbitrary channels.
    
    Note: any driver that cannot report channel noise should not report
    any value at all, e.g. made-up -92 dBm.
