I did get it working some time ago. The key is that, unless you're using a
wm(4) device which has code to support SIOCSIFADDR(AF_INET), you have to
manually set the ethernet address on the underlying interfaces to be the same
as the agr(4) one (which should default to the ethernet address of the first
port added to the agr, but this can be chanegd).
