Go read the code. The BSD code is a common reference. What you really have is a 64-bit "control field" and that is broken into a 32-bit flow, and another 32 bit field that has a 16-bit length, 8-bit Protocol, and 8-bit TTL. The 32-bit flow has 4-bits of Version, 8-bits of TOS, and ???? The ???? is alignment to the 32-bit boundary, it happens to be 20 bits. The code should be easy to fix up to make something more useful.
