From d268c1f5cfc92eb5bb605f7365769aacd93be234 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 9 May 2022 20:57:38 -0700 Subject: net: add CONFIG_DEBUG_NET This config option enables network debugging checks. This patch adds DEBUG_NET_WARN_ON_ONCE(cond) Note that this is not a replacement for WARN_ON_ONCE(cond) as (cond) is not evaluated if CONFIG_DEBUG_NET is not set.
