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

func ChecksumDefault(buf []byte, initial uint16) uint16

func Combine(a, b uint16) uint16

Combine combines the two uint16 to form their checksum. This is done by adding them and the carry.

Note that checksum a must have been computed on an even number of bytes.

func Put(b []byte, xsum uint16)

Put puts the checksum in the provided byte slice.
