Required with + * %NL80211_CMD_NAN_SET_LOCAL_SCHED to provide the raw NAN Availability + * attribute. Used by the device to publish Schedule Update NAFs. + * @NL80211_ATTR_NAN_SCHED_DEFERRED: Flag attribute used with + * %NL80211_CMD_NAN_SET_LOCAL_SCHED. When present, the command is a + * request from the device to perform an announced schedule update. This + * means that it needs to send the updated NAN availability to the peers, + * and do the actual switch on the right time (i.e. at the end of the slot + * after the slot in which the updated NAN Availability was sent). Since + * the slots management is done in the device, the update to the peers + * needs to be sent by the device, so it knows the actual switch time. + * If the flag is not set, the schedule should be applied immediately. + * When this flag is set, the total number of NAN channels from both the + * old and new schedules must not exceed the allowed number of local NAN + * channels, because with deferred scheduling the old channels cannot be + * removed before adding the new ones to free up space. + * @NL80211_ATTR_NAN_SCHED_UPDATE_SUCCESS: flag attribute used with + * %NL80211_CMD_NAN_SCHED_UPDATE_DONE to indicate that the deferred + * schedule update completed successfully.
