Introduce multi-buffer support for xdp running in generic mode not always linearizing the skb in netif_receive_generic_xdp routine. Introduce generic percpu page_pools allocator. Changes since v8: - fix veth regression introduce in veth.sh selftest Changes since v7: - fix sparse warnings Changes since v6: - remove patch 4/5 'net: page_pool: make stats available just for global pools' - rename netif_skb_segment_for_xdp() in skb_cow_data_for_xdp()/skb_pp_cow_data() - rename net_page_pool_alloc() in net_page_pool_create() - rename page_pool percpu pointer in system_page_pool - set percpu page_pool memory size Changes since v5: - move percpu page_pool pointer out of softnet_data in a dedicated variable - make page_pool stats available just for global pools - rely on netif_skb_segment_for_xdp utility routine in veth driver Changes since v4: - fix compilation error if page_pools are not enabled Changes since v3: - introduce page_pool in softnet_data structure - rely on page_pools for xdp_generic code Changes since v2: - rely on napi_alloc_frag() and napi_build_skb() to build the new skb Changes since v1: - explicitly keep the skb segmented in netif_skb_check_for_generic_xdp() and do not rely on pskb_expand_head() Lorenzo Bianconi (4): net: add generic percpu page_pool allocator xdp: rely on skb pointer reference in do_xdp_generic and netif_receive_generic_xdp xdp: add multi-buff support for xdp running in generic mode veth: rely on skb_pp_cow_data utility routine drivers/net/tun.c | 4 +- drivers/net/veth.c | 74 +------------------ include/linux/netdevice.h | 2 +- include/linux/skbuff.h | 4 ++ include/net/page_pool/types.h | 3 + net/core/dev.c | 131 +++++++++++++++++++++++++++------- net/core/page_pool.c | 23 ++++-- net/core/skbuff.c | 97 ++++++++++++++++++++++++- 8 files changed, 231 insertions(+), 107 deletions(-)
