      Description

      Ponsim is not trapping DHCP packets to the controller (SEBA-269). 

      Downstream DHCP packets are QinQ-tagged.  They are supposed to be trapped to the controller at the OLT and then forwarded to the ONU using Ponsim's packet-out().  Right now packet-out() is just encapsulating the QinQ-tagged packet with an additional 802.1Q layer (with vlan_vid = UNI port ID) before sending to the ONU.  A default rule at the ONU strips this VLAN tag and forwards the packet to the UNI port.  As a result the packets are still QinQ-tagged at the UNI port. 

      I believe a reasonable solution is to strip off the existing QinQ headers before adding the new 802.1Q header.
