thunderx: setup xdp_rxq_info

Browse source

This driver uses a bool scheme for "enable"/"disable" when setting up
different resources.  Thus, the hook points for xdp_rxq_info is done
in the same function call nicvf_rcv_queue_config().  This is activated
through enable/disable via nicvf_config_data_transfer(), which is tied
into nicvf_stop()/nicvf_open().

Extending driver packet handler call-path nicvf_rcv_pkt_handler() with
a pointer to the given struct rcv_queue, in-order to access the
xdp_rxq_info data area (in nicvf_xdp_rx()).

V2: Driver have no proper error path for failed XDP RX-queue info reg,
as nicvf_rcv_queue_config is a void function.
