Set the configuration for the EFI IPv6 network stack running on the communication
|
|
device this EFI IPv6 Configuration Protocol instance manages.
|
|
|
|
This function is used to set the configuration data of type DataType for the EFI
|
|
IPv6 network stack running on the communication device this EFI IPv6 Configuration
|
|
Protocol instance manages.
|
|
|
|
The DataSize is used to calculate the count of structure instances in the Data for
|
|
some DataType that multiple structure instances are allowed.
|
|
|
|
This function is always non-blocking. When setting some type of configuration data,
|
|
an asynchronous process is invoked to check the correctness of the data, such as
|
|
doing Duplicate Address Detection on the manually set local IPv6 addresses.
|
|
EFI_NOT_READY is returned immediately to indicate that such an asynchronous process
|
|
is invoked and the process is not finished yet. The caller willing to get the result
|
|
of the asynchronous process is required to call RegisterDataNotify() to register an
|
|
event on the specified configuration data. Once the event is signaled, the caller
|
|
can call GetData() to get back the configuration data in order to know the result.
|
|
For other types of configuration data that do not require an asynchronous configuration
|
|
process, the result of the operation is immediately returned.

- Data is NULL.

data type indicated by DataType.

configuration data can not be set under the current policy

data is already in process.

indicated by DataType.
