Description Paolo Bonzini 2010-08-09 19:15:47 UTC 
The following patches upstream implement gratuitous ARP notification.  They would be useful in RHEL5 and RHEL6 as well.

eefef1cf (net: add ARP notify option for devices, 2009-02-01)
a21090cf (ipv4: arp_notify address list bug, 2009-10-07)

http://kerneltrap.org/mailarchive/linux-netdev/2010/5/26/6278031

The last three are scheduled for merge in 2.6.36 (http://www.spinics.net/lists/netdev/msg137066.html).
