Instead it is recommended to use at least kernel 4.4. It is also already over 4 years old but still maintained by the stable kernel team. All older kernels (v3.16 - v4.3) should therefore be dropped to reduce the support overhead.

[batctl] master: batctl: Disable automatic destruction of empty meshifs (51b0746)

Repository : ssh://git@diktynna/batctl On branch : master >--------------------------------------------------------------- commit 51b07466550480d5b141a2d216f276f57c93a5c3 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Jun 13 17:59:35 2020 +0200 batctl: Disable automatic destruction of empty meshifs The sysfs interface of batman-adv used an automatic drop of empty batadv meshifs. This was necessary because no other method to remove this type of interface was available. The same behavior was tried to emulate in the batctl rtnetlink implementation to make the migration easier. But this caused problems with both (rtnetlink/sysfs) backends because the caller might not be aware of the current state of hardifs list for the current meshif. The meshif might therefore be deleted accidentally (and its configuration lost) even when the caller only wanted to swap some devices around. Instead print information about the necessary addition steps to drop the empty meshif instead of performing it automatically.
