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
