For virtio-input devices, writing to config area is defined as selecting config pages. But in virtio over shmem implement, this operation is not supported. The W/A is to update config area upon config selection in BE, and delay a short while after cfg write in FE. This delay does not reduce performance as it only happens during init stage.
