CPU Resource Profiling
This feature allows the user to optimize the use of the device according to the specific application.
For instance this will enable to allocate more ACL resources (up to 4K) in cases that routing
resources are not needed and vice versa, it will enable to allocate more routing resources in cases
that ACL resources are not needed.
