crypto: vmac - Make VMAC work when blocks aren't aligned
VMAC implementation, as it is, does not work with blocks that are not multiples of 128-bytes. Furthermore, this is a problem when using the implementation on scatterlists, even when the complete plain text is 128-byte multiple, as the pieces that get passed to vmac_update can be pretty much any size. I also added test cases for unaligned blocks. Signed-off-by: Salman Qazi <sqazi@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
