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.
