Not only in hfin. My SPU-AES has the same bug. Do you know someone who
wants to chain? I can remember that you said once "that this is
currently the case but we can change this since IPsec brings a new IV
for ever packet".
So, both of us have to fix it or must the crypto users complete their
encryption/decryption process in one go once they use async (we have no
documentation so we are very flexible here I guess :) )?
