Any bulk data path should be using the async interface, otherwise performance will seriously suffer should SIMD be unavailable. I think someone should look at converting wireless to async like IPsec. > Truth is though, I know very little about what changes would be > needed to make it do async decrypt, so maybe it would be a simple > matter? IPsec was actually quite straightforward. Cheers, -- Email: Herbert Xu Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
