> + * gnutls_transport_set_ktls:

If I was using this method, then I expect it would be upfront at the same time as initializing the transport. IOW before handshake. 

WRT to whether to return an error or do automatic fallback, personally I'd tend towards "do the right thing". I tend to view KTLS as a "nice to have" optimization, rather than a "must have" feature, so want it to be tried, but if not possible, transparently fallback.

If there are people, however, that view KTLS as something more critical, then they might want strong guarantees.

Perhaps it could motivate a extra param

  @required: 1 if KTLS is  mandatory, 0 if KTLS is optional

?
