From fcb30aa4da732d279527feba01cacc7dc996d137 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Sun, 16 Jan 2022 00:08:56 +0100 Subject: [PATCH] unix: fix meshing with wireguard/point-to-point interfaces Wireguard interfaces have no BROADCAST flag. We can also mesh on point-to-point links. That is why we mesh now also on interfaces with the IFF_POINTOPOINT flag enabled.
