C++ (Cpp) eth_prepare_mac_addr_change Examples

Example #1

/**
 * eth_mac_addr - set new Ethernet hardware address
 * @dev: network device
 * @p: socket address
 *
 * Change hardware address of device.
 *
 * This doesn't change hardware matching, so needs to be overridden
 * for most real devices.

	if (ret < 0)
		return ret;
