Name	Type	Description
PaddingInserter	simple module	Adds padding to packets to ensure they meet a minimum length requirement or to round up to a specific length. This module calculates the required padding length based on the packet's current length and the configured parameters. If padding is needed, it adds either a ByteCountChunk (for byte-aligned padding) or a BitCountChunk (for bit-level padding) at the specified position (front or back of the packet). This is commonly used in protocols that require packets to have a minimum size or to align to specific boundaries.
