Due to historical reasons, the implementation of XDP in virtio-net is relatively chaotic. For example, the processing of XDP actions has two copies of similar code. Such as page, xdp_page processing, etc. The purpose of this patch set is to refactor these code. Reduce the difficulty of subsequent maintenance. Subsequent developers will not introduce new bugs because of some complex logical relationships. In addition, the supporting to AF_XDP that I want to submit later will also need to reuse the logic of XDP, such as the processing of actions, I don't want to introduce a new similar code. In this way, I can reuse these codes in the future. This patches are developed on the top of another patch set[1]. I may have to wait to merge this. So this patch set is a RFC. Please review. Thanks.
