I guess it depends on what exactly the traffic is, but software-bridging
traffic from a network segment with >4k devices on OpenBSD seems a tad
optimistic. Try with dlg's suggestion if you like, but maybe at a time
when users of more than 8 thousand devices won't be too upset.

Normally one would want to reduce the number of devices in the segment -
realistically the broadcast or multicast traffic for address resolution
will get a bit much (especially if wifi is involved) - and even ignoring
that, it implies the amount of traffic is such that you'd usually want
an actual switch (and a reasonably decent one at that).
