Now this loop looks like:
while (TRUE) {
Status = NetworkInterfaceGetSubnetInfo (ThisNetworkInterfaceIntn,
ImageHandle); // Get subnet info
if (EFI_ERROR (Status)) {
if (Cond) {
break;
}
continue;
}
ThisNetworkInterface->IsIpv6 = FALSE;
if (CheckIsIpVersion6 (ThisNetworkInterfaceIntn)) {
ThisNetworkInterface->IsIpv6 = TRUE;
}
CopyMem ((VOID *)&ThisNetworkInterface->MacAddress,
&ThisNetworkInterfaceIntn->MacAddress,
ThisNetworkInterfaceIntn->HwAddressSize);
NetworkInterfaceGetSubnetInfo (ThisNetworkInterfaceIntn,
ImageHandle); // Get subnet info.
....
It seems the second call NetworkInterfaceGetSubnetInfo() is not required.

Mike.
