Hi all:

     During qinq testing , I got following error, and VM ping VM fail, I guess the reason is the "pop_vlan && ct(zone=XXX)" action not supported by kernel module. As the pop_vlan action just pop the outer vlan, and the pkt with remained inner vlan  cannot do ct action. So the icmp request pkt  with double vlan tags be dropped by kernel . Am I right ?
     My OS is CentOS 7.3 and kernel version is "3.10.0-514" , conntrack version is v1.4.4.

    Many Thanks for anyone could help !
