//$Review (nsun) Now we just print "Autonet address is in use" if autonet. 
// we don't send Dhcp broadcast.
// Maybe later we should send the Dhcp broadcast to see if the Dhcp server works or not
// for all DHCP enabled card

HRESULT
AutonetTest(NETDIAG_PARAMS* pParams, NETDIAG_RESULT*  pResults)
//++
//
//  Routine Description:
//
//      Checks if we have autonet addresses on all adapters. If we do than 
//      the workstation couldn't reach a DHCP server on any adapters.
//      Potential HW or NDIS issue.
//    
//  Arguments:
//
//      None.
//
//  Return Value:
//
//      S_FALSE :   Test failed, all adapters are autoconfigure.
//      S_OK    :   Test succeeded, we found at least one non-autoconfigure.
//      other   :   error codes
//
