4 All nodes now enable ``arp_accept`` sysctl setting to help with honoring
5 gratuitous ARP packets in their ARP tables. While sources of gratuitous ARP
6 packets are diverse, this comes especially useful for Neutron floating IP
7 addresses that roam between devices, and for which Neutron L3 agent sends
8 gratuitous ARP packets to update all network nodes about IP address new
9 locations.
