[DTS][PATCH V2 0/5] Improve checksum validate and tso packet counting.

[Ke Xu <ke1.xu@intel.com>]

This patch updates checksum_validate method and remove the tunnel one.

Use packet.show(dump) methods and packet reading to validate the
 packets in a faster, more common and more stable way. This allows
 packets other than the plain packets can be verified by method
 checksum_validate. This updated method replaces checksum_validate_tunnel
 in checksum offload cases.

This patch also updates TSO packet checking. Replace the tcpdump
 implementation to a packet reading implementation.

Packet reading implementation is more common to use when to verify the
 received packet count and payload size. The tcpdump method is not
 able to recognize some of the tunnel packets, leading to a wrong output
 failing the validation. Newly added tcpdump_analyse_sniff method is
 implemented by sniff packet reading and analysing and can replace
 the lagacy methods number_of_packets and number_of_bytes.

This patch also removes a redundant variable.
