The CCM document should give a warning to
users that in no condition the value M can be set to zero.
The field for M allows for such a value, and this value
signifies a max of 2^{-16} probability of success of message
integrity forgery. An unsuspecting user
may venture using the value M=0, unless informed with a warning.
The document currently mentions that M=0 is not a valid value.
