It allows applications to offload traffic redirection between DPDK ports in hardware, while optionally modifying it (e.g. performing encap/decap). For this to work, involved DPDK ports must be part of the same switch domain, as is the case with port representors, and the transfer attribute must be requested on flow rules. Also since the mlx5 switch is controlled through Netlink instead of Verbs, and given how tedious formatting Netlink messages is, a new dependency is added to mlx5: libmnl. See relevant patch. v2 changes: - Mostly compilation fixes for missing Netlink definitions on older systems. - Reduced stack consumption. - Adapted series to rely on mlx5_dev_to_port_id() instead of mlx5_dev_to_domain_id(). - See relevant patches for more information.
