From e4b817804579624b47823d87e647ec6c3d3ab827 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Thu, 27 Jul 2023 10:13:42 +0200 Subject: [PATCH] batman-adv: Avoid magic value for minimum MTU 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.
