+ * power save is enabled, the stack will not check for beacon loss and the
+ * driver needs to notify about loss of beacons with ieee80211_beacon_loss().
+ *
+ * The time (or number of beacons missed) until the firmware notifies the

+ * by mac80211 and the roaming algorithm in the future.
+ *
+ * Since there may be constantly changing information elements that nothing
+ * in the software stack cares about, we will, in the future, have mac80211
+ * tell the driver which information elements are interesting in the sense
+ * that we want to see changes in them. This will include
+ * - a list of information element IDs
+ * - a list of OUIs for the vendor information element
+ *
+ * Ideally, the hardware would filter out any beacons without changes in the
+ * requested elements, but if it cannot support that it may, at the expense
+ * of some efficiency, filter out only a subset. For example, if the device
+ * doesn't support checking for OUIs it should pass up all changes in all
+ * vendor information elements.
+ *
+ * Note that change, for the sake of simplification, also includes information
+ * elements appearing or disappearing from the beacon.
+ *
+ * Some hardware supports an "ignore list" instead, just make sure nothing
+ * that was requested is on the ignore list, and include commonly changing
+ * information element IDs in the ignore list, for example 11 (BSS load) and
+ * the various vendor-assigned IEs with unknown contents (128, 129, 133-136,
+ * 149, 150, 155, 156, 173, 176, 178, 179, 219); for forward compatibility
+ * it could also include some currently unused IDs.
+ *
+ *
+ * In addition to these capabilities, hardware should support notifying the
+ * host of changes in the beacon RSSI. This is relevant to implement roaming
+ * when no traffic is flowing (when traffic is flowing we see the RSSI of
+ * the received data packets). This can consist in notifying the host when
+ * the RSSI changes significantly or when it drops below or rises above
+ * configurable thresholds. In the future these thresholds will also be
+ * configured by mac80211 (which gets them from userspace) to implement
+ * them as the roaming algorithm requires.
+ *
+ * If the hardware cannot implement this, the driver should ask it to
+ * periodically pass beacon frames to the host so that software can do the
