Comment # 9 on bug 9119 from 
Looks good, so far. If it helps, I'll try and prepare some more trace files to
support implementing InAutoPoll (Response).

I suspect that you could also reuse the FeliCa dissector for dealing with the
Polling payload appropriately, since the data/commands seem to be largely the
same, as in the InListPassiveTarget response.
