But IP expects the phy layer to have low packet error rate, which
is usually not the case on radio links (IP cannot distinguish
packet loss due to bit errors and due to congestion, and assumes
the latter).
So for links over more than one radio link, VC with hop2hop ack
(and redundant frame remover) is vastly better than DG.
