XDP for idpf is currently 6 chapters: * convert Rx to libeth; * convert Tx and stats to libeth; * generic XDP and XSk code changes (you are here); * generic XDP and XSk code additions; * actual XDP for idpf via new libeth_xdp; * XSk for idpf (via ^). Part III does the following: * improve &xdp_buff_xsk cacheline placement; * does some cleanups with marking read-only bpf_prog and xdp_buff arguments const for some generic functions; * allows attaching already registered XDP memory model to RxQ info; * makes system percpu page_pools valid XDP memory models; * starts using netmems in the XDP core code (1 function); * allows mixing pages from several page_pools within one XDP frame; * optimizes &xdp_frame layout and removes no-more-used field. Bullets 4-6 are the most important ones. All of them are prereqs to libeth_xdp.
