Need to work out a way to calculate some TCP re-transmission stats . its problem because all worker threads run in-dependently

SACK counter might be a good proxy for retransmissions https://github.com/fmadio/pcap2json/commit/0bed656642fafbc7d3c9bd060d6c3c972a21de8c

Its a problem because of the wide parallel execution and exact TCP gap detection requires full serialization. Serialization burden the processing overhead.

See how it looks for production traffic
