The HMAC needs a message length parameter just like CMAC #944

The CMAC specification contains the following:

   |           |                        |        |          |          |
   | msgLen    | The CMAC message       | Domain | 0-524288 | No       |
   |           | lengths supported in   |        |          |          |
   |           | bits.                  |        |          |          |
   |           | Min/max/increment and  |        |          |          |
   |           | values must be mod 8.  |        |          |          |
   |           |                        |        |          |          |

The HMAC specification should also contain an identical min, max, inc specification for the message length so we can thoroughly and correctly test our HMAC hardware given our specific use cases.

Thank you.
