+The log2 of the key derivation rate. This is used by the key
+derivation to determine how ofen a new session key has to be
+generated. A value of -1 means to generate only one key and use
+it forever. The default is 0 which means to calculate a new key
+for every packet. A value of 1 would tell the key derivation
+to generate a new key after 2 packets, for 2 its 4 packets and 
+so on.
