+ Connect a class of devices using the platform Boot Manager policy.
+
+ The ConnectDeviceClass() function allows the caller to request that the Boot
+ Manager connect a class of devices.
+
+ If Class is EFI_BOOT_MANAGER_POLICY_CONSOLE_GUID then the Boot Manager will
+ use platform policy to connect consoles. Some platforms may restrict the
+ number of consoles connected as they attempt to fast boot, and calling
+ ConnectDeviceClass() with a Class value of
EFI_BOOT_MANAGER_POLICY_CONSOLE_GUID
+ must connect the set of consoles that follow the Boot Manager platform
policy,
+ and the EFI_SIMPLE_TEXT_INPUT_PROTOCOL, EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL,
and
+ the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL are produced on the connected handles.
+ The Boot Manager may restrict which consoles get connect due to platform
policy,
+ for example a security policy may require that a given console is not
connected.
+
+ If Class is EFI_BOOT_MANAGER_POLICY_NETWORK_GUID then the Boot Manager will
+ connect the protocols the platforms supports for UEFI general purpose network
+ applications on one or more handles. If more than one network controller is
+ available a platform will connect, one, many, or all of the networks based
+ on platform policy. Connecting UEFI networking protocols, like
EFI_DHCP4_PROTOCOL,
+ does not establish connections on the network. The UEFI general purpose
network
+ application that called ConnectDeviceClass() may need to use the published
+ protocols to establish the network connection. The Boot Manager can
optionally
+ have a policy to establish a network connection.
+
+ If Class is EFI_BOOT_MANAGER_POLICY_CONNECT_ALL_GUID then the Boot Manager
+ will connect all UEFI drivers using the UEFI Boot Service
+ EFI_BOOT_SERVICES.ConnectController(). If the Boot Manager has policy
+ associated with connect all UEFI drivers this policy will be used.
+
+ A platform can also define platform specific Class values as a properly
generated
+ EFI_GUID would never conflict with this specification.
+
+ @param[in] This A pointer to the EFI_BOOT_MANAGER_POLICY_PROTOCOL instance.
+ @param[in] Class A pointer to an EFI_GUID that represents a class of devices
+ that will be connected using the Boot Mangers platform
policy.
+
+ @retval EFI_SUCCESS At least one devices of the Class was connected.
+ @retval EFI_DEVICE_ERROR Devices were not connected due to an error.
+ @retval EFI_NOT_FOUND The Class is not supported by the platform.
