[dts] [PATCH V1] tests/rxtx_offload: add -c params when use tcpdump read pcap file

[lihong]

The tcpdump capture all the tx packets from testpmd, read the pcap
file will use too much time, and it not need to read all the packet
in the pcap file. Using 1024 packets to verify the tx packets is enough.
