SMBIOS/DMI: add type 41 = Onboard Devices Extended Information
From version 2.6 of the SMBIOS standard, type 10 (On Board Devices
Information) becomes obsolete. The reason for this is that no further
fields can be added to this structure without adversely affecting existing
software's ability to properly parse the data.
Therefore type 41 (Onboard Devices Extended Information) was added.
The structure is as follows:
struct smbios_type_41 {
u8 type;
u8 length;
u16 handle;
u8 reference_designation_string;
u8 device_type; /* same device type as in type 10 */
u8 device_type_instance;
u16 segment_group_number;
u8 bus_number;
u8 device_function_number;
};
