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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
