[scapy] Linux-Cooked pcap to ethernet

# The pcap file formatted by "Linux cooked"
# tcpdump -r myfile.pcap -nn
reading from file event1.pcap, link-type LINUX_SLL (Linux cooked)
...
...

# step1. read myfile.pcap
pkts = rdpcap("myfile.pcap");
# step2. read myfile.pcap
pkts = [Ether(src='00:11:22:33:44:55', dst='22:33:44:55:66:77')/pkt[1:] for pkt in pkts]
# step3. modify IP address and recalculate chksum
for pkt in pkts:
pkt[1].dst='192.168.1.10';
pkt[1].src='192.168.1.1';
del pkt[IP].chksum
del pkt[UDP].chksum
# step4. packet send
sendp(pkts[0]);

# step5. save pcap

wrpcap("output.pcap",pkts);

# tcpdump -r output.pcap -nn

reading from file output.pcap, link-type EN10MB (Ethernet)

# pkt[1:] : It means IP layer

1) Before: Linux cooked / IP / UDP / UDP-Data

2) After: Ethernet / IP / UDP / UDP-Data
