Generic xmit is a bit hard to follow so here are three clean ups to start with making this code more friendly. Thanks, Maciej Maciej Fijalkowski (3): xsk: avoid overwriting skb fields for multi-buffer traffic xsk: remove @first_frag from xsk_build_skb() xsk: wrap generic metadata handling onto separate function net/xdp/xsk.c | 109 +++++++++++++++++++++++++++----------------------- 1 file changed, 60 insertions(+), 49 deletions(-) -- 2.43.0
