There seems to be something else going on here- ix0.221 should've showed the
inbound traffic (with or without my fixes) since that gets tapped in
ether_input_internal before entering the bridge at all. The general flow here
*should* look like:

external -> ix0:ether_input_internal -> ix0:ether_demux -> vlan_input ->
ix0.221:ether_input_internal -> bridge2:bridge_input -> tap0:ether_demux

You've observed the traffic getting tapped at the second step above, then
there's a disconnect somewhere after that.
