Add tlen field into struct tso_t, and change tso_start() to return skb_transport_offset(skb) + tso->tlen This removes from callers the need to use tcp_hdrlen(skb) and will ease UDP segmentation offload addition. v2: calls tso_start() earlier in otx2_sq_append_tso() [Jakub] Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
