OTG: RX stats missing in flow statistics even though port is recieving

[bkreddy143]

Seeing RX stats missing in flow statistics even though stats are received on port .
Script seeing issue is :

In this test , CreateFlow creates a raw tx only port mode raw traffic flow with no rx port specified .
func (a *testArgs) createFlow(t *testing.T, name, dstMac string) string {
flow := a.top.Flows().Add().SetName(name) flow.Metrics().SetEnable(true) flow.Size().SetFixed(300) e1 := flow.Packet().Add().Ethernet() e1.Src().SetValue(atePort1.MAC) flow.TxRx().Port().SetTxName("port1") <<<<<<< e1.Dst().SetChoice("value").SetValue(dstMac) v4 := flow.Packet().Add().Ipv4() v4.Src().SetValue(atePort1.IPv4) v4.Dst().SetValue(dstPfxMin) a.ate.OTG().PushConfig(t, a.top)
I believe since Rx port is not specified , Rx stats is not expected in this case of generating 1-arm test traffic. The 0 Rx in the logged o/p in this case should not be relevant to test pass/fail. Test/pass in this test appears to be driven by port stats on rx test ports using the port metrics and not the flow metrics.
Please let us know if test is passing or not and if failing , is it failing in some other point e.g. verifying port metrics on OTG ports.
