2022-05-31	net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na	Arun Ajith S	1	-12/+11
	RFC 9131 changes default behaviour of handling RX of NA messages when the corresponding entry is absent in the neighbour cache. The current implementation is limited to accept just unsolicited NAs. However, the RFC is more generic where it also accepts solicited NAs. Both types should result in adding a STALE entry for this case. Expand accept_untracked_na behaviour to also accept solicited NAs to be compliant with the RFC and rename the sysctl knob to accept_untracked_na.

2022-04-17	net/ipv6: Introduce accept_unsolicited_na knob to implement router-side ↵	Arun Ajith S	1	-0/+255
	changes for RFC9131 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.
