Long answer. A checksum also sometimes referred to as a hash is an alphanumeric value that uniquely represents the contents of a file.

Since this checksum function is only used for TCP packets, there is no need for supporting packets larger than 65535 bytes. Rather than adding needless overflow checks, you should restrict the bytes parameter by making that a uint16_t. Note that both the original code and your improvement only work on big endian implementations, unless some outside code byteswapped the whole TCP packet, in.

I see a number of things that may help you improve your code. Use better names. The name execute is too generic and not at all suggestive of the purpose of the function.
