+ *
+ * Description: Broadcom Network Interface Card Extension (NICE) is an
+ *              extension to Linux NET device kernel mode drivers.
+ *              NICE is designed to provide additional functionalities,
+ *              such as receive packet intercept. To support Broadcom NICE,
+ *              the network device driver can be modified by adding an
+ *              device ioctl handler and by indicating receiving packets
+ *              to the NICE receive handler. Broadcom NICE will only be
+ *              enabled by a NICE-aware intermediate driver, such as
+ *              Broadcom Advanced Server Program Driver (BASP). When NICE
+ *              is not enabled, the modified network device drivers
+ *              functions exactly as other non-NICE aware drivers.
