} dmi_firmware_features_t;Description
The dmi_firmware_features_t union holds the set of the features the
platform firmware supports, as the platform firmware information structure
(type 0) of SMBIOS gives them. It is the type of the features field of
dmi_firmware_t. Each bit, when set, tells that the feature is supported.
Bits 32 to 47 of the value are reserved for the firmware vendor, and bits 48
to 63 for the system vendor; they have no members, and are only available in
__value.
