Stats collection matching fails if in-port used without device name prefix

If we use in-port, without device name e.f in-port=1, rather then in-port=openflow:1:1, stats collection matching fails and it augment the flow under the alien id. Here is the example flow.

{
"id": "flow1",
"table_id": 0,
"hard-timeout": 0,
"priority": 30400,
"idle-timeout": 0,
"instructions": {
"instruction": [
{
"order": 0,
"apply-actions": {
"action": [
{
"order": 1,
"set-field": {
"protocol-match-fields":

{ "mpls-label": 324001 }

}
}
]
}
},
{
"order": 1,
"go-to-table":

{ "table_id": 1 }

}
]
},
"match": {
"in-port": "1",
"ethernet-match": {
"ethernet-type":

{ "type": 2054 }

}
},
