I'm currently developping a plugin and I have a little question: Is
it possible, from a given dissector, to get the number of bytes already
dissected by lower-layer dissectors ? In other words, can I get the
index relative to start of a frame/packet buffer? From my dissector
point of view, for instance, the relative index to the start of the
tvbuff passed to it is of course 0, which could be let's say index 50
relative to the absolute start of the ethernet frame/packet.
What if the packet your dissector has been given has been reassembled
from data in multiple link-layer frames? In that case, it's not clear
the question you're trying to ask in your dissector *has* an answer.
What are you planning to do with that value?
