Passes capsules to the firmware with both virtual and physical mapping. Depending on the intended
consumption, the firmware may process the capsule immediately. If the payload should persist
across a system reset, the reset value returned from EFI_QueryCapsuleCapabilities must
be passed into ResetSystem() and will cause the capsule to be processed by the firmware as
part of the reset process.

EFI_CAPSULE_BLOCK_DESCRIPTOR that describes the
location in physical memory of a set of capsules.
