* 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.
