skip over non-mcast/down/ipfw0 netif when joining
net/syncthing can panic FreeBSD 12.2-RELEASE-p7 GENERIC amd64 when it attempts to perform IPv6 multicast join on ipfw0 interface.
please consider including attached patch until kernel grows some resilience against such nonsensical actions.
Thank you for the report and patch Alex
What is the user impact of this (other than, of course, the lack of a panic), with respect to syncthing functionality changes, if any, for users with this setup?
Proposed patch has no impact on app's function
