With mlx5 it is also possible to offload a limited set of flow rules to the mlxsw (or E-switch) using the same DPDK flow commands. A 'transfer' attribute was added to the flow rule creation command in order to distinguish between configuring port flows and E-switch flows. The commands destined for the E-switch are transposed to TC-flower rules and are send, as Netlink messages, to the mlx5 driver, or more precisely to the netdev which represent the mlxsw port. With the addition to the PMD of E-switch configuration via DR (direct verbs rules) it is now possible to configure the E-switch using these commands instead of using TC-Flower messages. Doing so will allow us to remove the TCF support and the dependency of libmnl from the PMD. The purpose of this RFC is to propose configuring the E-switch flow filtering using DR, to remove the TCF support from the PMD and to remove the dependency of the PMD in libmnl. As for today VLAN insertion or removal is not supported in DR, this support will be added in separate commits.
