1129 | * DOC: Beacon filter support | ||
1130 | * | ||
1131 | * Some hardware have beacon filter support to reduce host cpu wakeups | ||
1132 | * which will reduce system power consumption. It usuallly works so that | ||
1133 | * the firmware creates a checksum of the beacon but omits all constantly | ||
1134 | * changing elements (TSF, TIM etc). Whenever the checksum changes the | ||
1135 | * beacon is forwarded to the host, otherwise it will be just dropped. That | ||
1136 | * way the host will only receive beacons where some relevant information | ||
1137 | * (for example ERP protection or WMM settings) have changed. | ||
1138 | * | ||
1139 | * Beacon filter support is informed with %IEEE80211_HW_BEACON_FILTER flag. | ||
1140 | * The driver needs to enable beacon filter support whenever power save is | ||
1141 | * enabled, that is %IEEE80211_CONF_PS is set. When power save is enabled, | ||
1142 | * the stack will not check for beacon miss at all and the driver needs to | ||
1143 | * notify about complete loss of beacons with ieee80211_beacon_loss(). | ||
