From Francesco Fondelli (bug 2349):

Attached is a patch to export packets data as "C Arrays".  I often have
the need to [re]send data captured with wireshark using a raw/pf_packet socket.
Output format is one char[] per packet, it looks like almost the same as
the one produced by "Follow TCP stream".
