From 8d487b4cc5b896cff5277adef6dd491b5918381f Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Wed, 23 Feb 2022 09:06:28 +0100 Subject: [PATCH] networking: use OPENVPN_ETH_ALEN instead of ETH_ALEN With the introduction of SITNL two occurrences of ETH_ALEN were introduced in the code. This define exists on Linux in the linux/if_ether.h header, however the latter is included in linux/if_tun.h which may or may not exist (depending on how old your system is). If the system lacks if_tun.h then the compilation fails because ETH_ALEN cannot be found. For this reason, swap ETH_ALEN with OPENVPN_ETH_ALEN which is already used in other places of the code.
