Sorry to hear of you issue. We need the exact device ID for the NIC's to start with. So you are saying that even in promiscuous mode the packets are not received correct? Where are the packets being dropped? By the HW or by the stack? You can use ethtool and netstat to see where they are being dropped.
Let us know about the ID and if you can find where the packets are being dropped. Thanks.
