[dts][PATCH V1 0/2] tests/tso: modify get_chksum_value_and_verify to fix a checksum-verify error and improve the performance

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

Function get_chksum_value_and_verify in test suite TSO case test_tso_tunneling 
 cannot verify checksum error. Duplicated call to packet.read_pcapfile will
 change the packet sequence stored in packet.pktgen.pkts, leading to a wrongly
 organized packet sequence writen to file, and fails the following checksum
 verifying.

The wrongly used methods also lead to a low effeciency. Duplicated call to
 packet.read_pcapfile will lengthen the packet sequence stored in
 packet.pktgen.pkts. Duplicated call to packet.save_pcapfile is also time
 consuming.

There is also a misuse of show method that *.show() will print a packet info,
 but will not return a string. The *.show will return a method object, and the
 following str(out) will turn the method object into a string, so here when use
 out = x.show, checksum looking up in str(out) it is equivalent to that in
 repr(x).

In the first commit, the checksum verifying problem is fixed.

In the second commit, this function is improved that the case running time is
 decresed by 2 minutes.
