I've got a question about the s390 hmac implementation. How does the hardware tell if it's the first update (where the cv from the param block contains undefined state) or not? Is it a bit in s390_kmac_gr0 or is it the imbl? Thanks, -- Email: Herbert Xu Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
