If you change the relevant sysctls both via sysctl.d and via networkd then they will constantly step on each other's toes. Hence, if you let networkd manage your interface then let networkd manage your interface. Moreover, there's already a udev rule in place to re-apply network sysctls as those interfaces appear, no need to add one manually. Lennart -- Lennart Poettering, Berlin
