No it's just because nobody has gotten around to complete the async hash work yet. So we're currently half-way through the process of converting existing algorithms to the shash interface, which allows them to be used efficiently by IPsec through the ahash interface. Once that's completed we can then convert IPsec (or rather, authenc) over to using ahash.
