With the addition of parsing ongoing TCP sessions, it may be the case that the start of the packets does not correspond with the start of the DNS query, because of various TCP buffering or delayed sending that can happen in the kernel.

This deliverable will implement additional ways of handling ongoing TCP sessions by trying to find the DNS query and response within the stream.
