ustatusd

This daemon provides ubus notifications on OpenWrt systems. There is also a
small cli tool that will show all notifications on stdout. Currently the
following notifications are generated.

* network
  - 'network.link': {"ifname":"br-lan","carrier":0}	// carrier down
  - 'network.link': {"ifname":"br-lan","carrier":1}	// carrier up

* routing
  - 'route.new': {"interface":"br-lan","dst":"192.168.1.0","netmask":24,"ipv4":1}
  - 'route.new': {"interface":"br-lan","dst":"fdcf:244c:a484:0:0:0:0:0","netmask":64,"ipv6":1}
  - 'route.del ': {"interface":"br-lan","dst":"192.168.1.0","netmask":24,"ipv4":1}
  - 'route.del': {"interface":"br-lan","dst":"fdcf:244c:a484:0:0:0:0:0","netmask":64,"ipv6":1}

  - 'key-mismatch': {"address":"00:18:84:88:00:03"}
  - 'local-deauth': {"address":"00:18:84:88:00:03"}


There is also a uci file that defines timeouts and thresholds

cat /etc/config/ustatus
config global
	option rssi_low		40	// threshold for low rssi
	option rssi_high	150	// threshold for high rssi
	option tx_rate_low	64000	// threshold for low tx rates
	option tx_rate_high	144400  // threshold for high tx rate
	option tx_retries	10	// threshold for tx retrys
	option station_status	5	// timeout for polling bssid rssi/rate/retry info
	option station_poll	30	// timeout for wifi.status.station notifications
