> In some situations, we would get several ip fragments， which total
> data length is less than minimum frame(64) and padding with zeros.
> Examples: Second Fragment is "a0a1 a2a3 a4a5 a6a7 0000 0000 ..."
> and Third Fragment is "a8a9 aaab acad aeaf b0b1 b2b3 ...".
> And then, we would reassemble Second and Third Fragment like this
> "a0a1 a2a3 a4a5 a6a7 0000 0000 ... a8a9 aaab acad aeaf b0b1 ...",
> which is not correct! So, we need recalculate the data length 
> of fragment to remove invalid padings(zero)!
