/*++
Routine Description:
Allows the user to set controller specific options for a controller that a
driver is currently managing.
Arguments:
This - A pointer to the EFI_DRIVER_CONFIGURATION2_PROTOCOL instance.
ControllerHandle - The handle of the controller to set options on.
ChildHandle - The handle of the child controller to set options on. This
is an optional parameter that may be NULL. It will be NULL
for device drivers, and for a bus drivers that wish to set
options for the bus controller. It will not be NULL for a
bus driver that wishes to set options for one of its child
controllers.
Language - A pointer to a three character RFC 3066 language identifier.
This is the language of the user interface that should be
presented to the user, and it must match one of the languages
specified in SupportedLanguages. The number of languages
supported by a driver is up to the driver writer.
ActionRequired - A pointer to the action that the calling agent is required
to perform when this function returns. See "Related
Definitions" for a list of the actions that the calling
agent is required to perform prior to accessing
ControllerHandle again.
Returns:
EFI_SUCCESS - The driver specified by This successfully set the
configuration options for the controller specified
by ControllerHandle..
EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ActionRequired is NULL.
EFI_UNSUPPORTED - The driver specified by This does not support setting
configuration options for the controller specified by
ControllerHandle and ChildHandle.
EFI_UNSUPPORTED - The driver specified by This does not support the
language specified by Language.
EFI_DEVICE_ERROR - A device error occurred while attempt to set the
configuration options for the controller specified
by ControllerHandle and ChildHandle.
EFI_OUT_RESOURCES - There are not enough resources available to set the
configuration options for the controller specified
by ControllerHandle and ChildHandle.

Routine Description:
Tests to see if a controller's current configuration options are valid.
Arguments:
This - A pointer to the EFI_DRIVER_CONFIGURATION2_PROTOCOL instance.
ControllerHandle - The handle of the controller to test if it's current
configuration options are valid.
ChildHandle - The handle of the child controller to test if it's current
configuration options are valid. This is an optional
parameter that may be NULL. It will be NULL for device
drivers. It will also be NULL for a bus drivers that wish
to test the configuration options for the bus controller.
It will not be NULL for a bus driver that wishes to test
configuration options for one of its child controllers.
Returns:
EFI_SUCCESS - The controller specified by ControllerHandle and
ChildHandle that is being managed by the driver
specified by This has a valid set of configuration
options.
EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_UNSUPPORTED - The driver specified by This is not currently
managing the controller specified by ControllerHandle
and ChildHandle.
EFI_DEVICE_ERROR - The controller specified by ControllerHandle and
ChildHandle that is being managed by the driver
specified by This has an invalid set of configuration
options.

Routine Description:
Forces a driver to set the default configuration options for a controller.
Arguments:
This - A pointer to the EFI_DRIVER_CONFIGURATION2_PROTOCOL instance.
ControllerHandle - The handle of the controller to force default configuration options on.
ChildHandle - The handle of the child controller to force default configuration options on This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for a bus drivers that wish to force default configuration options for the bus controller. It will not be NULL for a bus driver that wishes to force default configuration options for one of its child controllers.
DefaultType - The type of default configuration options to force on the controller specified by ControllerHandle and ChildHandle. See Table 9-1 for legal values. A DefaultType of 0x00000000 must be supported by this protocol.
ActionRequired - A pointer to the action that the calling agent is required to perform when this function returns. See "Related Definitions" in Section 9.1for a list of the actions that the calling agent is required to perform prior to accessing ControllerHandle again.
Returns:
EFI_SUCCESS - The driver specified by This successfully forced the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ActionRequired is NULL.
EFI_UNSUPPORTED - The driver specified by This does not support forcing the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_UNSUPPORTED - The driver specified by This does not support the configuration type specified by DefaultType.
EFI_DEVICE_ERROR - A device error occurred while attempt to force the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_OUT_RESOURCES - There are not enough resources available to force the default configuration options on the controller specified by ControllerHandle and ChildHandle.

Protocol Description:
Used to set configuration options for a controller that an EFI Driver is managing.
Parameters:
SetOptions - Allows the use to set drivers specific configuration
options for a controller that the driver is currently
managing.
OptionsValid - Tests to see if a controller's current configuration
options are valid.
ForceDefaults - Forces a driver to set the default configuration options
for a controller.
