Which is the code that produces the warning messages Gilson de Paiva 
saw, of course.  I'm quite willing to believe that FreeBSD's loop 
detection works great for the situation where bridged interfaces are put 
on the same subnet.

Spanning tree protocol, link aggregation (or "port trunking", etc), and 
other layer-2 stuff found in managed switches still have their uses.

For some odd reason, a Tom Lehrer song about Werner von Braun is coming 
to mind-- "FreeBSD forwards the packets, who cares whether they loop 
around."  :-)
