Instead of directly accessing the field Will allow PacketTunnelType to hold the precise tunnel type like DECODE_TUNNEL_ERSPANII with a modification of PacketIsTunnelChild
So that we know for a packet which precise type of tunnel it is (like erspan2).
ebpf program does not handle 3 layers of vlan
Ticket: 7717 Allows for instance to process/log ARP packets over VXLAN. That means we need to decode the ethernet layer above vxlan instead of skipping it as part of the vxlan, even if the vxlan decoder still checks the ethernet layer to avoid FPs.
