xdp_frags_tsize field will be used to store paged frame truesize for xdp_buff/xdp_frame. In order to not increase skb_shared_info size we will use a hole due to skb_shared_info alignment. gso_type filed will be used to store paged frame size. This is a preliminary patch to properly support xdp multi-buff Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> --- include/linux/skbuff.h | 2 ++ 1 file changed, 2 insertions(+)
