DataTracker::advance_sequence removes too much data

[GreaterThanOrEqual]

I have a case where there are missing packets in my capture. The original tcp stream was fine. I receive server_out_of_order_callback after the missing packet but it may take a while before I realize that the problem is with capture (I track acks on the client flow). The packets are stored in buffered_payload_. The problem is when I call advance_sequence, the first stored packet in buffered_payload_ is removed. I think if (seq_compare(it->first, seq) <= 0) in advance_sequence should be if (seq_compare(it->first, seq) < 0)
