| | 61 | Starts running the configuration policy for the EFI IPv4 Protocol driver.\r |
| | 62 | \r |
| | 63 | The Start() function is called to determine and to begin the platform \r |
| | 64 | configuration policy by the EFI IPv4 Protocol driver. This determination may \r |
| | 65 | be as simple as returning EFI_UNSUPPORTED if there is no EFI IPv4 Protocol \r |
| | 66 | driver configuration policy. It may be as involved as loading some defaults \r |
| | 67 | from nonvolatile storage, downloading dynamic data from a DHCP server, and \r |
| | 68 | checking permissions with a site policy server.\r |
| | 69 | Starting the configuration policy is just the beginning. It may finish almost \r |
| | 70 | instantly or it may take several minutes before it fails to retrieve configuration \r |
| | 71 | information from one or more servers. Once the policy is started, drivers \r |
| | 72 | should use the DoneEvent parameter to determine when the configuration policy \r |
| | 73 | has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to \r |
| | 74 | determine if the configuration succeeded or failed.\r |
| | 75 | Until the configuration completes successfully, EFI IPv4 Protocol driver instances \r |
| | 76 | that are attempting to use default configurations must return EFI_NO_MAPPING.\r |
| | 77 | Once the configuration is complete, the EFI IPv4 Configuration Protocol driver \r |
| | 78 | signals DoneEvent. The configuration may need to be updated in the future, \r |
| | 79 | however; in this case, the EFI IPv4 Configuration Protocol driver must signal \r |
| | 80 | ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default \r |
| | 81 | configurations must return EFI_NO_MAPPING until the configuration policy has \r |
| | 82 | been rerun.\r |
