# setHardwareAddress(const IOEthernetAddress *)

Sets or changes the station address used by the Ethernet controller.

## Declaration

```occ
virtual IOReturn setHardwareAddress(
 const IOEthernetAddress *addrP); 
```

## Parameters

- `addrP`: Pointer to an IOEthernetAddress containing the new station address.

## Return Value

Return Value The default implementation will always return kIOReturnUnsupported. If overridden, drivers must return kIOReturnSuccess on success, or an error return code otherwise.

## Overview

Overview This method is called in response to a client command to change the station address used by the Ethernet controller. Implementation of this method is optional. This method is called from the workloop context.
