From fb2780721ca5e9f78bbe4544b819b929a982df9c Mon Sep 17 00:00:00 2001 From: Victor Nogueira Date: Sat, 16 Dec 2023 17:44:34 -0300 Subject: net: sched: Move drop_reason to struct tc_skb_cb Move drop_reason from struct tcf_result to skb cb - more specifically to struct tc_skb_cb. With that, we'll be able to also set the drop reason for the remaining qdiscs (aside from clsact) that do not have access to tcf_result when time comes to set the skb drop reason.
