Function decodeBFD

layers/bfd.go:306–321

decodeBFD analyses a byte slice and attempts to decode it as a BFD control packet If it succeeds, it loads p with information about the packet and returns nil. If it fails, it returns an error (non nil). This function is employed in layertypes.go to register the BFD layer.

(data []byte, p gopacket.PacketBuilder)

//
// This function is employed in layertypes.go to register the BFD layer.
func decodeBFD(data []byte, p gopacket.PacketBuilder) error {

	// Attempt to decode the byte slice.
	d := &BFD{}
	err := d.DecodeFromBytes(data, p)
	if err != nil {
		return err
	}

	// If the decoding worked, add the layer to the packet and set it
	// as the application layer too, if there isn't already one.
	p.AddLayer(d)
	p.SetApplicationLayer(d)

	return nil
}
