From: Linus Lüssing Date: Tue, 9 Jan 2024 21:58:59 +0000 (+0100) Subject: batman-adv: mcast: fix mcast packet type counter on timeouted nodes X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=59f7ea703c38abc3f239068d49cc8897740e4c54;p=linux.git 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.
