Title:
  native OpenFlow does not support resubmit to previous tables

Status in neutron:
  Invalid

Bug description:
  When moving traffic between the OpenFlow tables it can be necessary to move traffic back to an earlier table to be reprocessed.
  This action is supported when using the ofctl implementation however when the of_interface is set to native the follow error is thrown:
  RuntimeError: ofctl request version=0x4,msg_type=0xe,msg_len=0x40,xid=0x4bd1c40f,OFPFlowMod(buffer_id=4294967295,command=0,cookie=13554728807927189788,cookie_mask=0,flags=0,hard_timeout=0,idle_timeout=0,instructions=[OFPInstructionGotoTable(len=8,table_id=50,type=1)],match=OFPMatch(oxm_fields={}),out_group=0,out_port=0,priority=5,table_id=60) error OpenFlow errors [OFPErrorMsg(code=2,data=bytearray(....),type=3)]
