There is no good answer to this question. Generally, you must be sure that
you don't break anything.
So you must test the code paths you have changed.

FreeBSD testing is required when patching common EAL, scripts or makefiles.

These files are part of the base driver.
The rule is to not patch them and try to do the changes in PMD only.
There can be exceptions if an Intel maintainer acknowledges it.
