During the mutlicast test for HLK , i am receiving zero packets on mine virtual miniport driver .
I am using NDIS 6.2 virtual miniport driver . I am handling OID_802_3_MULTICAST_LIST set request correctly . but still i driver still receive zero packet .
#define VELAN_MAX_MCAST_LIST 32
#define MUX_MAC_ADDRESS 6
ULONG MaximumListSize = 32 ;
ULONG m_ulMclistSize;
UCHAR m_ulMcList[VELAN_MAX_MCAST_LIST][MUX_MAC_ADDRESS];
case OID_802_3_MAXIMUM_LIST_SIZE:
Information = &MaximumListSize;
InformationLength = sizeof(MaximumListSize);
This is my set handling :
***************************************************
status = NDIS_STATUS_SUCCESS;
OidRequest->DATA.SET_INFORMATION.BytesNeeded = MUX_MAC_ADDRESS;
OidRequest->DATA.SET_INFORMATION.BytesRead = OidRequest->DATA.SET_INFORMATION.InformationBufferLength;
OID_802_3_MULTICAST_LIST :
do
{
//check multicast address invalid
if(OidRequest->DATA.SET_INFORMATION.InformationBufferLength % MUX_MAC_ADDRESS){
OidRequest->DATA.SET_INFORMATION.BytesRead = 0;
status = NDIS_STATUS_INVALID_LENGTH;
break;
}
//check multicast address list full
if(OidRequest->DATA.SET_INFORMATION.InformationBufferLength > (VELAN_MAX_MCAST_LIST * MUX_MAC_ADDRESS)){
status = NDIS_STATUS_MULTICAST_FULL;
OidRequest->DATA.SET_INFORMATION.BytesNeeded = VELAN_MAX_MCAST_LIST * MUX_MAC_ADDRESS;
break;
}
//setting new multicast address list
NdisZeroMemory(m_ulMcList,VELAN_MAX_MCAST_LIST * MUX_MAC_ADDRESS);
NdisMoveMemory(m_ulMcList,OidRequest->DATA.SET_INFORMATION.InformationBuffer,OidRequest->DATA.SET_INFORMATION.InformationBufferLength);
m_ulMclistSize = OidRequest->DATA.SET_INFORMATION.InformationBufferLength / MUX_MAC_ADDRESS;
status = NDIS_STATUS_SUCCESS;
}while(FALSE);
**********************************************************
and for query request :
Information = &m_ulMcList[0];
InformationLength = m_ulMclistSize *sizeof(MUX_MAC_ADDRESS);
and my error log :

*****************************************************
after that i am getting receive log :
Send/Receive for all valid multicast addresses. Should receive all packets for this test.
50013 Received less than the expected percentage of packets sent.
We expected 247 packets (99 percent of 250 expected packets sent).
NDISTest header module: Destination 01-02-03-04-00-00 on test adapter Virtual Network Driver received 0 of 250 expected packets sent.
******************************************************************
i don’t know why . I am handling all the things . Any thing am missing ? any suggestions ?
