HCK- 2 machine checkconnectivity issue

In HCK 2 machine checkconnectivity test has failed. Failed sub test is(send and receive packets test)
I am writing driver for Mobile broadband device with USB interface (Cdc-NCM driver -> Ethernet type driver).
In send and receive sub test, IPX type packets are sent to support machine.
In my device didn’t see any IPX packets coming OUT from USB BULKOUT pipe, verified using usb beagle log.

For oid of OID_GEN_PHYSICAL_MEDIUM returned NdisPhysicalMedium802_3

In inf the below values are set
Characteristics = 0x84 ; NCF_PHYSICAL + NCF_HAS_UI
BusType = 15
*IfType = 6 ;
*MediaType = 0 ; NdisMedium802_3
*PhysicalMediaType = 14 ; NdisPhysicalMedium802_3

  1. Is the above values are correct?
  2. Why didn’t receive any IPX packets from NDIS?
    But Message analyzer verified IPX packets going to NDIS.
    Normal TCP/UDP is working properly.
