pub const VIRTIO_DEVICE_TYPE_SPECIFIC_FEATURES_MASK: u64 = 0xfffc_0000_00ff_ffff;Expand description
Virtio feature bits that are specific to a device type.
Per virtio 1.2 spec, features 0 to 23 and 50 to 127 are feature bits for the specific device
type. Features beyond 63 are not representable in the current u64 type used to store sets of
features, so bits 64 to 127 are not included in this mask.
