The current implementation of
"colinux-bridged-net-daemon.exe" (from
http://www.colinux.org/snapshots/devel-coLinux-20051013.exe
) mirrors broadcast packets back: A broadcast packet
sent from the colinux instance within Windows to the
Windows networking will get mirrored back to the
colinux instance.

Thus, linux thinks that some other network member has
the same MAC address, and spits out warning messages
like "eth0: duplicate address detected!", which pollute
the kernel log buffer and log files.

Previous versions of "colinux-bridged-net-daemon.exe"
(http://www.colinux.org/snapshots/stable-coLinux-20050524.exe
AFAIK) did not mirror back broadcast packets. (However,
the performance of previous
"colinux-bridged-net-daemon.exe" versions was miserable.)
