> +Fortville: Support of RX Packet Filtering using VMDQ & DCB Features
> +===============================================================
> ====
> +
> +The Intel Network Interface Card(e.g. XL710), supports a number of
> +packet filtering functions which can be used to distribute incoming
> +packets into a number of reception (RX) queues. VMDQ & DCB is a pair of
> +such filtering functions which operate on VLAN-tagged packets to
> +distribute those packets to RX queues.
> +
> +The feature itself works by:
> +
> +- splitting the incoming packets up into different "pools" - each with
> +its own
> +  set of RX queues - based upon the VLAN ID within the VLAN tag of the
> packet.
> +- assigning each packet to a specific queue within the pool, based upon
> +the
> +  user priority field within the VLAN tag.
> +
> +The VMDQ & DCB features are enabled in the ``vmdq_dcb`` example
> +application contained in the DPDK, and this application should be used
> +to validate the feature.
