Hey Andrew, Since you're on lagg(4) a bit, could you perhaps have a look at this thread from last year on -net@: https://lists.freebsd.org/pipermail/freebsd-net/2017-June/048284.html I've been asked by several people that were using WiFi-CopperNet failover which worked fine in FreeBSD 10.x but was broken since then. I'm not an src committer nor a network stack expert in this area nor I'm using lagg(4), but perhaps you could expedite on handling this or at least point us to a more appropriate channel (due to lack of interest on -net@). ./danfe
