It is not just for fallback, I plan to support the IPsec GSO codepath for software crypto too. In this case we should be able to handle all algorithms, including the async ones. > This path is going to be slower that the path were you do the crypto in > advance, right? If the cryptd is used, yes. At least that's what I messured for IPsec forwarding. But I think this is because we enqueue requests much faster that the cryptd dequeues them.
