The PMD Power Management scheme currently has 3 modes,
scale, monitor and pause. However, it would be nice to
have a baseline mode for easy comparison of power savings
with and without these modes.

This patch adds a 'baseline' mode were the pmd power
management is not enabled. Use --pmg-mgmt=baseline.
