This was since we replaced the image. However, now that there is a single image, this is no longer needed. Note that RSC is sent separately in a new command. This solves issues with newer devices that support PN offload. Since driver re-sent the keys, the PN got zeroed and the receiver dropped the next packets, until PN caught up again.
