External queue is a queue that is managed by a process external to PMD, but uses PMD process to generate its flow rules. For the hardware to allow the DPDK process to set rules for it, the process needs to use the same PD of the external process. In addition, the indexes of the queues in hardware are represented by 32-bit compared to the rte_flow indexes represented by 16-bit, so the processes need to share some mapping between the indexes. These patches allow the external process to provide devargs which enable importing its context and PD, instead of prepare new ones. In addition, an API is provided for mapping for the indexes of the queues. v1: - initial commits. v2: - Rebase. - Add ABI exception for common/mlx5 library. - Correct DevX flag updating. - Improve explanations in doc and comments. - Remove teatpmd part. v3: - Rebase. - Fix compilation error. - Avoide TOCTOU issue in external RxQ map/unmap functions. - Add check it the queue still referenced in unmapping function. - Improve guide explanations for the new devargs.
