Fortunately, Linux isn't Windows......you are going to find lots of
Windows "standard" protocols that aren't documented nor supported by
anyone else.

Well, Microsoft did.....there is RFC2131 that describes how you are
supposed to use an ARP to respond to a duplicate IPv4 used on the
network.  It is commonly used to ensure you don't have systems
manually configured or not honoring leases when DHCP is handing out
dynamic IP addresses.  Everyone else seems to implement this properly.

That's because it implements the standard protocols by default.

Run DHCP or properly manually configure your Linux system.  I don't
know how old your Linux kernel is for the 8xx, but this support for
RFC2131 has been in Linux for a very long time.


Thanks.
