UADP 2.0 Packet Buffer

What does Up to mean? Does it mean 8 MB per core and up to four cores per switch SKU? Slide is from a BRKARC-3467 talk in June 2017. I think it means 16 MB per slice (32 MB total) for UADP-2.XL and 8 MB per slice for UADP-2.0.

25 percent of the buffer is allocated to the ring connection. So buffer available for burst absorption is ~10 MB per slice for the XL and ~5 MB per slice for UADP-2.0.
