Hi,
I set tag 0 on port tapVm72 and tapVm71, and then send ping packets with vlan
100 from tapVm72 to tapVm71. But ovs-tcpdump cannot capture any packets with
vlan on tapVm72. It seems that vlan check is failed in mirror_packet(), because
tapVm72 is an access port and the vlan packets are dropped. This is not
reasonable because OVS does not use NORMAL forward. When using custom OpenFlow
tables, mirror action should not consider tag configuration.
