Subject: [PATCH 3/7] batman-adv: Avoid magic value for minimum MTU
Date: Wed, 16 Aug 2023 18:39:56 +0200	[thread overview]
Message-ID: <20230816164000.190884-4-sw@simonwunderlich.de> (raw)
In-Reply-To: <20230816164000.190884-1-sw@simonwunderlich.de>

From: Sven Eckelmann <sven@narfation.org>

The header linux/if_ether.h already defines a constant for the minimum MTU.
So simply use it instead of having a magic constant in the code.
