You can specify the table by combining it with the command in the higher bits
def augment_command_with_table_id(command, table_id):
return (int(table_id) << 8) + int(command)
cmd = self.augment_command_with_table_id(ofproto.OFPFC_ADD, 10)
datapath.send_flow_mod(rule=<Match>, command=cmd)
However if you're target is OVS, I'd recommend you switch to openflow
1.3 and use groups and buckets for multipathing. The group select in
openvswitch is still a symetric l4 hash.
Happy Hacking!
