If representor matching was enabled (device argument repr_matching_en is equal to 1, default configuration), then during registration of external SQs, mlx5 PMD would not create control flow rules in NIC Tx domain. This caused an issue with packet metadata. If a packet sent on external SQ had packet metadata attached, then it would be lost when it would go from NIC Tx to FDB domain.
Meanwhile, the external SQ flow rules should be managed individually and not be destroyed internally by PMD. This series fixes these two issues for the external SQ flow rules in rte_pmd_mlx5_external_sq_enable().
