From: "Rao, Lei" <lei....@intel.com>
The data pointer has skipped vnet_hdr_len in the function of
parse_packet_early().So, we can not subtract vnet_hdr_len again
when calculating pkt->header_size in fill_pkt_tcp_info(). Otherwise,
it will cause network packet comparsion errors and greatly increase
the frequency of checkpoints.
