Add a new neighbour cache entry in STALE state for routers on receiving an unsolicited (gratuitous) neighbour advertisement with target link-layer-address option specified. This is similar to the arp_accept configuration for IPv4. A new sysctl endpoint is created to turn on this behaviour: /proc/sys/net/ipv6/conf/interface/accept_unsolicited_na.
Do we really need to expose this to /proc/sys, for every interface added in the host ?
/proc files creations/deletion cost a lot in environments adding/deleting netns very often.
I would prefer using NETLINK attributes, a single recvmsg() syscall can fetch/set hundreds of them.
