| 10 | * Description: Broadcom Network Interface Card Extension (NICE) is an |
| 11 | * extension to Linux NET device kernel mode drivers. |
| 12 | * NICE is designed to provide additional functionalities, |
| 13 | * such as receive packet intercept. To support Broadcom NICE, |
| 14 | * the network device driver can be modified by adding an |
| 15 | * device ioctl handler and by indicating receiving packets |
| 16 | * to the NICE receive handler. Broadcom NICE will only be |
| 17 | * enabled by a NICE-aware intermediate driver, such as |
| 18 | * Broadcom Advanced Server Program Driver (BASP). When NICE |
| 19 | * is not enabled, the modified network device drivers |
| 20 | * functions exactly as other non-NICE aware drivers. |
