previous table:

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)
