From 043e397e48c58b4442ea5124dc1bdc95367a0a33 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sat, 28 Jan 2023 10:58:33 -0500 Subject: net: sched: use skb_ip_totlen and iph_totlen There are 1 action and 1 qdisc that may process IPv4 TCP GSO packets and access iph->tot_len, replace them with skb_ip_totlen() and iph_totlen() accordingly. Note that we don't need to replace the one in tcf_csum_ipv4(), as it will return for TCP GSO packets in tcf_csum_ipv4_tcp().
