Implement rekeying of connections with the RxGK security class. This involves regenerating the keys with a different key number as part of the input data after a certain amount of time or a certain amount of bytes encrypted. Rekeying may be triggered by either end. The LSW of the key number is inserted into the security-specific field in the RX header, and we try and expand it to 32-bits to make it last longer.
