For others,
Avati is now working on a user-space gratuitous ARP daemon for mini
BMCs that doesnt support GARPs. You will be able to provide a list of
IP addresses that has to be GARP'd in the config file. If you want to
understand more about GARP, follow these links...

Looking at the tcpdump for SR870BN4 (192.168.1.60) (Tiger4 Quad
Itanium2 platform), Intel's Sahalee BMC (IPMI-1.5) uses "Request Based
Gratuitous ARP". So in your initial release of garpd use this approach
We will plan for "Response Based Gratuitous ARP" in the next release.
