Now that digest_null has a setkey we no longer need to do that. In fact when only confidentiality is specified for ESP we already use digest_null directly. However, when the null algorithm is explicitly specified by the user we still opt for hmac(digest_null). This patch removes this discrepancy. I have not added a new compat name for it because by chance it wasn't actualy possible for the user to specify the name hmac(digest_null) due to a key length check in xfrm_user (which I found out when testing that compat name :) Signed-off-by: Herbert Xu Signed-off-by: David S.
