Introduce page_pool support in veth driver in order to recycle pages in veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb through the page allocator when we run a xdp program on the device and we receive skbs from the stack. Change since v1: - remove page_pool checks in veth_convert_skb_to_xdp_buff() before allocating the pages - recycle pages in the hot cache if build_skb fails in veth_convert_skb_to_xdp_buff() Lorenzo Bianconi (2): net: veth: add page_pool for page recycling net: veth: add page_pool stats drivers/net/Kconfig | 2 ++ drivers/net/veth.c | 68 ++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 63 insertions(+), 7 deletions(-) -- 2.40.0
