The first two patches do not provide new functionality for the user (except the logs are reworked). They are reworking to make the rxq scheduling and PMD auto load balance code more modular for cleanup and to be used by subsequent patches. They are also removing the code duplication between them by having some common functions they can both use.
1/5 reworks the current rxq scheduling code to make it more modular and reusable. 2/5 makes PMD auto load balance reuse the common rxq scheduling code and removes the duplication of the rxq scheduling code in PMD auto load balance for making a dry run. 3/5 adds a new option to assign rxqs to pmds that incorporates the estimated load of the PMD and removes the restriction for trying to equally distribute the number of rxqs across the PMDs. This means it is solely load based so will help optimize balancing the processing load across the PMDs. With this method, a group of low loaded rxqs may be on one PMD, while another PMD could have just one highly loaded rxq. 4/5 provides a fallback for if the user tries to pin an rxq to a PMD with pmd-rxq-affinity but the PMD is not in the pmd-cpu-mask. Previously it was not polled. 5/5 adds an option to non-isolate the PMD when it is pinned with an rxq using pmd-rxq-affinity.
