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