/**
|
|
Starts running the configuration policy for the EFI IPv4 Protocol driver.
|
|
|
|
The Start() function is called to determine and to begin the platform
|
|
configuration policy by the EFI IPv4 Protocol driver. This determination may
|
|
be as simple as returning EFI_UNSUPPORTED if there is no EFI IPv4 Protocol
|
|
driver configuration policy. It may be as involved as loading some defaults
|
|
from nonvolatile storage, downloading dynamic data from a DHCP server, and
|
|
checking permissions with a site policy server.
|
|
Starting the configuration policy is just the beginning. It may finish almost
|
|
instantly or it may take several minutes before it fails to retrieve configuration
|
|
information from one or more servers. Once the policy is started, drivers
|
|
should use the DoneEvent parameter to determine when the configuration policy
|
|
has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to
|
|
determine if the configuration succeeded or failed.
|
|
Until the configuration completes successfully, EFI IPv4 Protocol driver instances
|
|
that are attempting to use default configurations must return EFI_NO_MAPPING.
|
|
Once the configuration is complete, the EFI IPv4 Configuration Protocol driver
|
|
signals DoneEvent. The configuration may need to be updated in the future.
|
|
Note that in this case the EFI IPv4 Configuration Protocol driver must signal
|
|
ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default
|
|
configurations must return EFI_NO_MAPPING until the configuration policy has
|
|
been rerun.
|
|
|
|
@param This The pointer to the EFI_IP4_CONFIG_PROTOCOL instance.
|
|
@param DoneEvent Event that will be signaled when the EFI IPv4
|
|
Protocol driver configuration policy completes
|
|
execution. This event must be of type EVT_NOTIFY_SIGNAL.
|
|
@param ReconfigEvent Event that will be signaled when the EFI IPv4
|
|
Protocol driver configuration needs to be updated.
|
|
This event must be of type EVT_NOTIFY_SIGNAL.
