Description

PCAP files created while using af-packet v2/3 on tagged traffic do not include the vlan header. This is because the header is removed by the kernel and passed to us in an auxiliary data structure.

Similar to the AF_PACKET IPS mode we could forge the header back into the packet before it's written to disk.
