Receiving valid Multicast address failed on mini port driver

[vkp]

I am currently doing multicast address test in HLK test . During the test initially i can't able to add multicast address .So i handled set request OID_802_3_MULTICAST_LIST on miniport driver . So i can bale to add the address . But after that i got errors during the test .

This is the log :

After that Add as many multicast addresses as driver says it supports :
