- This is true when all the Apollos are connected via ethernet. However, in
- most Apollos installation, all nodes are connected via ATR and probably only
- one or few gateway nodes have direct interface to an ethernet. Therefore NFS
- traffic on non-ethernet gateway node still goes through DDS on ATR. I could
- be wrong if TCP/IP packet can be transferred directly as ATR tokens.
