And ofcourse the src mac of your packets should be 'that' mac as set above.

The NIC Card we are using is Intel Corporation 82576 Virtual Function (rev 01) Do we need to do now NIC/CPU low level debugging or is there some issue in = the sw that could cause the packet to be dropped below this log message.
