  The QueryCapsuleCapabilities() function allows a caller to test to see if a capsule or

  constructed where CapsuleImageSize is equal to HeaderSize that is equal to sizeof
  (EFI_CAPSULE_HEADER). To determine reset requirements,
  CAPSULE_FLAGS_PERSIST_ACROSS_RESET should be set in the Flags field of the
