> Extend basic structures of the driver (e.g. 'idpf_vport', 'idpf_*_queue',
> 'idpf_vport_user_config_data') by adding members necessary to support XDP.
> Add extra XDP Tx queues needed to support XDP_TX and XDP_REDIRECT
> actions without interfering with regular Tx traffic.
> Also add functions dedicated to support XDP initialization for Rx and Tx
> queues and call those functions from the existing algorithms of queues
> configuration.
