This is kind of brainstorming, but I guess we should make it clear when this function is called and what would be the desired behavior. For example:
- If this function is called *before* handshake, and a ciphersuite incompatible with KTLS is negotiated, maybe it makes sense to automatically fall back to non-KTLS implementation
- On the other hand, if this function is called *after* handshake is completed, it would be probably more useful to just return an error

@berrange do you have any opinion on the API?
