Wei Zhao - Dec. 4, 2018, 5:51 a.m.
There is need to add boundary for input number from commandline,
If it beyond the defination, code will return error.

Bad arguments
the rule failed to be created.
I tried TCP/SCTP rule, and got the same result.
  I tried validating the rule instead of creating the rules with wrong sport/dport, and got the same result.
The bug is fixed.

Why just not something like:
if (u > RTE_LEN2MASK(size * CHAR_BIT))
   return -1;
?
