Thanks for your input.  The 00:00:00:00:00:00 address is not used as 
the destination address of the frame, because I passed the -b option 
of the etherwake tool, and so the broadcast address was used.  Also, 
the frames generated by arping are broadcasted, and they don't reach tap1.

In my tests tap0 and tap1 are not used by any program that connects to 
them; the tap0 and tap1 interfaces have been added and are reported by 
ifconfig.  However, if I instruct qemu to use tap0, and then in the 
virutal machine I make the very same tests, I can see broadcast frames 
on tap1.
