[CRYPTO] null: Add null blkcipher algorithm
This patch adds a null blkcipher algorithm called ecb(cipher_null) for backwards compatibility. Previously the null algorithm when used by IPsec copied the data byte by byte. This new algorithm optimises that to a straight memcpy which lets us better measure inherent overheads in our IPsec code. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
