<p>
A virtual function to support parsing of arriving packets to determine if they should be kept in the queue and to dispatch events.
<p>
A generic header validity check (as specified in RFC 1889) is performed on every incoming packet. If the generic check completes succesfully, this method is called before the packet is actually inserted into the reception queue.<p>
May be used to perform additional validity checks or to do some application specific processing.<p>
