+  Modifies or resets the current station address, if supported.

+

+  This function modifies or resets the current station address of a network

+  interface, if supported. If Reset is TRUE, then the current station address is

+  set to the network interface's permanent address. If Reset is FALSE, and the

+  network interface allows its station address to be modified, then the current

+  station address is changed to the address specified by New. If the network

+  interface does not allow its station address to be modified, then

+  EFI_INVALID_PARAMETER will be returned. If the station address is successfully

+  updated on the network interface, EFI_SUCCESS will be returned. If the driver

+  has not been initialized, EFI_DEVICE_ERROR will be returned.

+

+  @param This  A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.

+  @param Reset Flag used to reset the station address to the network interface's

+               permanent address.

+  @param New   New station address to be used for the network interface.

+

+

+  @retval EFI_SUCCESS           The network interface's station address was updated.

+  @retval EFI_NOT_STARTED       The Simple Network Protocol interface has not been

+                                started by calling Start().

+  @retval EFI_INVALID_PARAMETER The New station address was not accepted by the NIC.

+  @retval EFI_INVALID_PARAMETER Reset is FALSE and New is NULL.

+  @retval EFI_DEVICE_ERROR      The Simple Network Protocol interface has not

+                                been initialized by calling Initialize().

+  @retval EFI_DEVICE_ERROR      An error occurred attempting to set the new

+                                station address.

+  @retval EFI_UNSUPPORTED       The NIC does not support changing the network

+                                interface's station address.
