> Today, it is possible to offload an interface flow rules to the hardware using
> DPDK flow commands.
> 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.
