func (*MySQL) GetUndiscoveredHosts ¶

func (r *MySQL) GetUndiscoveredHosts(expiration time.Duration) (result []net.IPNet, err error)

GetUndiscoveredHosts returns IP addresses whose physical location is still undiscovered or staled more than expiration. result can be nil on empty result.

func (*MySQL) Location ¶

func (r *MySQL) Location(mac net.HardwareAddr) (dpid string, port uint32, status network.LocationStatus, err error)

func (*MySQL) MAC ¶
