ethernet header length
When i capture a tcp packet (a normal ACK-RST packet), Snort shows me a total packet lenght of 3C(hex) = 60(dez) and an IpLen of 20(dez) and a TcpLen of 20(dez), so the sizeof the Ethernet header should be: TotalPacketLenght-(IpLen+TcpLen), that would be 60-(20+20) = 20, but i thought that the Ethernet header has a fixed sizeof 14. Whats going on with these 6 Bytes ?
