crypto: talitos - adaptation of talitos_submit() for SEC1
SEC1 descriptor is a bit different to SEC2+ descriptor. talitos_submit() will have to copy hdr field into hdr1 field and send the descriptor starting at hdr1 up to next_desc. For SEC2, it remains unchanged and next_desc is just ignored. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
