Note ==================================================== #. How to send packet with specific TPID with scapy:: 1. wrpcap("qinq.pcap",[Ether(dst="3C:FD:FE:A3:A0:AE")/Dot1Q(type=0x8100,vlan=1)/Dot1Q(type=0x8100,vlan=4092)/IP(src="192.168.0.1", dst="192.168.0.2")/Raw('x' * 20)]). 2. hexedit qinq.pcap; change tpid field, "ctrl+w" to save, "ctrl+x" to exit. 3. sendp(rdpcap("qinq.pcap"), iface="eth17").
