I'll claim correctness on a technicality ;)

Since the original statement was: "Notably only four of the six 100G 
ports on the 92160YCX will run at 100G, leaving two at 40G."

In the default mode, you get 4 x 40G + 2 x 100G. Good point that 
there is an optional mode which is 4 x 100G - but there is no 40G in 
that mode, ports 53-54 are disabled in that mode.

Thanks,
Tim
