Agree, please use dynamic logging, and also don't redefine new macros like DEBUG/INFO/WARN/ERROR.
Instead use PMD_DRV_LOG or equivalent macros.

The base rule here is that all drivers should look the same as much
as reasonably possible. This makes reviewers of other subsystems more likely
to see problems. It also allows for later changes where some developer does a global
improvement across many PMD's.

Drivers should not be snowflakes, each one is not unique.
