This patch series adds support for DLB v2.5 to the current DLB V2.0 PMD. The resulting PMD supports both hardware versions.
The main differences between the DLB v2.5 and v2.0 hardware are: - Number of queues/ports - DLB v2.5 uses a combined credit pool, whereas DLB v2.0 splits credits into 2 pools, a directed credit pool and a load balanced credit pool. - Different register maps, with different bit names and offsets In order to support both hardware versions with the same PMD, and avoid code duplication, the file dlb2_resource.c required a complete rewrite. This required some creative staging of the changes in order to keep the individual patches relatively small, while also meeting the requirement that all individual patches in the set compile cleanly. To accomplish this, a few temporary files are used: dlb2_hw_types_new.h dlb2_resources_new.h dlb2_resources_new.c As dlb2_resources_new.c is populated with the new combined v2.0/v2.5 low level logic, the corresponding old code is removed from dlb2_resource.c, thus allowing both the original and new code to continue to compile and link cleanly. Once all of the code has been migrated to the new model, the old versions of the files are removed, and the new versions are renamed, effectively replacing the old original files. As you review the code, you can ignore the code deletions from dlb2_resource.c, as that file continues to shrink as the new corresponding logic is added to dlb2_resource_new.c.
