Hello. In theory UAR should work fine under MacBSD, it needs a couple of
extra lines of code to switch on the Berkeley Packet Filter support (diffs
included below).

The problem, however, is getting a kernel that supports multicasts. From
a quick look at the current code, it seems as if a newer if_ae.c, ie:

	$NetBSD: if_ae.c,v 1.22 1995/04/13 03:58:18 briggs Exp $

has the necessary support. I'm running a slightly hacked NetBSD 1.0 but
I can probably get motivated to update to current and try it out.

As for CAP, it can also use BPF but the easiest path would be to get
UAR working, then CAP with UAR, then CAP standalone.

UAR etc. is on munnari.OZ.AU in mac/uar.tar.Z, see also
