It doesn't change the hw address...
it's the exact answer to the original question... how to make an ARP
broadcast such that suddenly traffic for a given IP comes to you...
Thanks for the pointer... I'd browsed the website, but never looked very
deep... the redundant_linux.txt file contains some fine ideas...

it doesn't "modify" the arp address... it just repeatedly broadcasts an
broadcast ARP for the IP address that it wants to takeover specifying it's
own MAC address... as long as this is done frequently enough that no host
has to actually request an ARP for that IP, then all traffic will go to
the "backup" ethernet card... it's a neat solution...
