passing through. Modifications are restricted to a subset of C language operations on unsigned integers of 8, 16, 32 or 64 bit size. These are: set to new value (=), addition (+=), subtraction (-=), multiplication (*=), division (/=), negation (= -), bitwise AND (&=), bitwise OR (|=), bitwise eXclusive OR (^=), shift left (<<=), shift right (>>=). Several operations are all applied to a packet sequentially in order they were specified by user.
