Module interface for protocol header checker components. Modules that implement this interface verify protocol-specific headers in packets and typically remove them after successful validation. These components act as packet filters that can drop invalid packets based on header information, ensuring protocol compliance and integrity. They are commonly used in protocol stacks to process incoming packets before passing them to higher layers.

Extends

Name	Type	Description
IPacketFilter	module interface	Interface for packet filter modules. A packet filter connects one input to one output. It can operate in both active and passive mode. Packets can be pushed into its input or packets can be pulled from its output. Processed packets are either dropped, if they don't match the filter criteria, or they are passed through without any delay or reordering. Packets are not modified in any way.
