Thanks, that did get me dumps that I assume are the outgoing packets.  I don't know anything really about NII, but I kind of naively assumed the debug output (at least of the data block) would look something like the hex dump of tshark -x but they are nowhere near alike.
Any pointers as to how to compare this with what we see on the wire would be greatly appreciated.
