This is the SNP interface routine for changing the NIC's mac address.
This routine basically retrieves snp structure, checks the SNP state and
calls the above routines to actually do the work
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.

NULL then this routine resets the mac address to the NIC's

@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.
