 That's not the correct fix, actually.  tap(4) _is_ a full Ethernet
 interface, and therefore should depend on arp just like all the others.
 
 I'll fix that in -current later tonight and request a pull-up.  I think
 I had that one before, and I probably fixed it on my laptop, but then
 forgot to commit it.  It's quite an unlikely configuration...
 
 Of course, there should be some way to deal with that directly from
 config(1).
