RFM69 automatic ACKing?

[WhiteHare]

I'm wondering if the radio can handle automatically ACKing on its own?  The demo code seems to have the arduino sending the ACK's, not the RFM69.  The datasheet makes just a single, vague reference to AutoRxACK, but it describes it as "automatic reception of acknowledge," which sounds different anyway.  Is that it, or does it go by some other name?

As a point of comparison, some  radios (e.g. NRF24L01+) do have the capability to auto ACK, and I'm trying to find out if the
RFM69 is one of them.

I believe the short answer is no. Hence it is done in the library. An ACK is just another packet with an extra flag, nothing special about it other than that.
