After reading the first frame, which we can do in two reads (software
plus hardware header, which tell us the length of the following data),
we can issue full packet reads. The software header contains a field
that informs us of the full length of the next frame that we can read,
so we can do that in a single sitting. This brings us down from three
SDIO read invocation to a single one per packet for a given RX stream.
