u80211d

a wifi introspection and scanning daemon for OpenWrt.

the following ubus calls are provided:
'wifi' @b95a57e0
	"assoclist":{"ifname":"String"}
	"scan":{"dump":"Boolean","ifname":"String"}
	"cac":{"ifname":"String","channel":"Integer","width":"Integer"}
	"reg":{"country":"String"}
	"iface":{"phy":"Integer","sta":"Boolean","ap":"Boolean","mon":"Boolean","add":"String","delete":"String"}

assoclist - return a list of stations associated with a BSS
{
	"xx:xx:xx:xx:xx:xx": {
		"mac": "xx:xx:xx:xx:xx:xx",
		"interface": "wlan0",
		"signal": 161,
		"inactive": 1130,
		"rx_pkt": 34,
		"tx_pkt": 16,
		"rx_rate": {
			"bitrate": 288200,
			"mhz": 80
		},
		"tx_rate": {
			"bitrate": 12000,
			"mhz": 20
		},
		"rx_bytes": 4836,
		"tx_bytes": 2362,
		"tx_retries": 45,
		"tx_failed": 0
	}
}

reg - can be used to get/set the 11D domain
{
	"country": "US",
	"dfs-region": 1
}

iface - return a list of all local wifi interfaces. it is also possible to
	create add/del interfaces using this call
{
	"wlan0": {
		"mac": "xx:xx:xx:xx:xx:x",
		"interface": "wlan0",
		"dbm": 30,
		"iftype": "ap"
	}
}

scan - trigger a site survey. once complete a notification will be broadcast.
       upon an event a dump can be read out. automated periodic scanning is
       also supported.
{
	{
		"mode": "master",
		"crypto": 1,
		"channel": 6,
		"ssid": "MyWifi",
		"bss_load": {
			"station_count": 7,
			"channel_utilization": true,
			"admission_capacity": 0
		},
		"wpa_version": 2,
		"auth_suites": "psk",
		"quality": 33,
		"quality_max": 70
	}
}

cac - trigger a DFS scan on a specific channel/width. upon completion a event
      is broadcast. automated periodic scanning is also supported.

the following events are generated
  - 'wifi.add.iface': {"mac":"00:18:84:88:00:02","dbm":20,"iftype":"ap"}
