Well tcpreplay will do that too (both uni and bi-directionally). If you
still want to write your own, it's pretty simple. The trick is to send
the packet using libnet_adv_write_link() which takes your libnet handle,
a data buffer containing your entire packet, and the lenght of the data
in the buffer.
Read do_packets() in do_packets.c in tcpreplay for more details.
