VistaCreek is the code name, the chip would be aria10.

Since mt bryce is the chip name, after more than 1 eASIC this becomes confusing.

Generally public product names should be used because only the early developers will know the development code names.

Not sure if this is dpdk style, i know some other project do this.

This works for self consistent headers, no idea if dpdk are.

don't bother with this.
