Ability to edit both inner and outer vlan tags.

[ckannan]

A captured packet has 2 vlan tags like this..

[root@localhost pcap]# tcpdump -nner vlan_double.pcap
reading from file vlan_double.pcap, link-type EN10MB (Ethernet)
-5:00:00.000000 3c:fd:fe:9e:10:09 > 3c:fd:fe:9c:c2:d9, ethertype 802.1Q (0x8100), length 1514: vlan 3333, p 0, ethertype 802.1Q, vlan 666, p 0, ethertype IPv4, 198.18.0.1.1234 > 198.18.1.1.5678: Flags [none], seq 129018:130470, win 1024, length 1452

I can use tcpreplay-edit and edit only the outer tag...

[root@localhost pcap]# tcpreplay-edit -i ens6f1 -t -K -l 0 --enet-vlan=add --enet-vlan-pri=0 --enet-vlan-tag=501 --enet-vlan-cfi=0 vlan_double.pcap

There doesn't appear to be a way to edit the inner tag as well.

Deferring request until a later release. Is there a practical use for this? Although support for playback of such a packet has recently been added, usefulness of a tcpreplay-edit option seem impractical. The we would have to also support triple, quadruple etc. Where will it stop?
