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@).
