Name	Type	Description
ChecksumCheckerBase	simple module	Base module for checksum checkers that verify the integrity of packets. This module filters packets based on their checksum value, dropping packets with invalid checksums. It supports multiple checksum algorithms such as CRC32 and the Internet checksum, and also several checksum modes: disabled, declared correct, declared incorrect, and computed. When in computed mode, it calculates the actual checksum and compares it with the received value.
