Modern tcpdump may issue zero for octets encoding length of IP datagramm that contains TCP packet captured with TCP Segmentation Offload enabled. tcpshow breaks due to signed underflow in such case. Fix it by using total length of captured packet from "length:" field instead of zero value from packet data.
