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,
however; in this case, the EFI IPv4 Configuration Protocol driver must signal
ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default
