[Intel-wired-lan] [next PATCH S92 6/9] i40e: fold prefix strings directly into stat names

Alice Michael alice.michael at intel.com

From: Jacob Keller <jacob.e.keller at intel.com>

We always prefix these stats with a fixed string, so just fold this
prefix into the stat string definition. This preparatory work will make
it easier to implement a helper function to copy stats and strings into
the supplied buffers in a future patch.
