Types

type CallbackFunc

type CallbackFunc func(data []byte) int

type NfLog

type NfLog struct {

	// The multicast address
	McastGroup int
	// contains filtered or unexported fields
}

NfLog

func NewNfLog

func (nflog *NfLog) Close()

Close the NfLog down

func (*NfLog) Loop

func (nflog *NfLog) Loop()

Receive packets in a loop until quit
