Hash key functionality

Hash keys can be used to distribute traffic flows to streams. Each hash key looks at a specific set of fields (as defined by the hash key in use) within the frame and calculates a hash value using the values of the fields as input to the hash function. This hash value is used for determining in which of the streams the specific packet is included. This ensures that packets from the same flow (as defined by the frame fields included in the given hash key) are always delivered to the same stream.
