Write the packets to a capture file

Capture the packets and write them to a capture file.

Note: Pcap.dumpOpen(String) will override if the "savefile" already exists; If you need to add a captured packet to the existing "savefile" you can use Pcap.dumpOpenAppend(String) instead.

Docs: libpcap, javadoc.
