I don't like the separate file, having rules with comments in a single
place is easier to maintain.
Why waive all changes in all mlx drivers?
There is a single issue with 20.02, see below.
Besides, looking at next patches, why keep experimental symbols?
If all symbols in common/mlx5 are for internal use, mark them _all_ as such=

This is not until 20.11 if we merge this patch now.
It is only when comparing 20.02 to 20.05.
After this, symbols will be marked INTERNAL and will be skipped by the
generic rule, so we can remove this exception in 20.08-rc0.

A stricter rule is enough, can you try something like:
+[suppress_file]
+ file_name_regexp =3D ^librte_common_mlx5\.
--=20
