Functions ¶

func Checksum ¶

func Checksum(data []byte, initial uint16) uint16

Checksum computes an IP checksum starting with the provided initial value. The length of data should be at least 128 bytes for best performance. Smaller buffers will still compute a correct result.

func PseudoHeaderChecksum ¶

func PseudoHeaderChecksum(protocol uint8, srcAddr, dstAddr []byte, totalLen uint16) uint16

PseudoHeaderChecksum computes an IP pseudo-header checksum. srcAddr and dstAddr must be 4 or 16 bytes in length.
