commit e6fbde1250b73c3c9f49fc5a22ad9a8b10f864d5 Author: Linus Lüssing linus.luessing@c0d3.blue Date: Tue Jan 9 22:58:59 2024 +0100

batman-adv: mcast: fix mcast packet type counter on timeouted nodes

When a node which does not have the new batman-adv multicast packet type capability vanishes then the according, global counter erroneously would not be reduced in response on other nodes. Which in turn leads to the mesh never switching back to sending with the new multicast packet type.

Fix this by reducing the according counter when such a node times out.
