[Users] broadcast messages on venet0

[Denis V. Lunev]

- broadcasts incoming to a VE are dropped
- outgoing broadcasts gone to the HWN like to the router and not routed
further as usual, so you'll see nothing in eth0. This is normal. The
interface if point-to-point so other VEs do not see this packet.

	Den
