The fresh skb gets the ip_summed = -CHECKSUM_NONE value, forcing network stack to recompute checksum, and -preventing my GRO patch to work. - -Fix is to make the ip_summed setting after skb copy. - -Note : rx_copybreak current value is 16383, so all frames are copied... - -Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> -Acked-by: Francois Romieu <romieu@fr.zoreil.com> -Signed-off-by: David S.
