This patch is the first step in the introduction of a new AEAD alg type. Unlike normal conversions this patch only renames the existing aead_alg structure because there are external references to it. Those references will be removed after this patch. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
