What about section 12.8 which says:
Note that for an algorithm that has a larger block size than 64 bits,
the equivalent function will be done with that entire block. For
example, a 16-octet block algorithm would operate on 16 octets, and
then produce two octets of check, and then work on 16-octet blocks.
