Two pieces of feedback here:
1. as stated on patch 2, this doc change should go with the code changes,
   so merge this patch into previous.
2. For the text itself, please point out that 256 is the default bitwidth
   in DPDK - just to ensure the user isn't confused that they need to pass
   extra parameters.

Thanks,
