H A Dndisc_unsolicited_na_test.shdiff 3e0b8f529c10037ae0b369fc892e524eae5a5485 Mon May 30 12:14:14 CEST 2022 Arun Ajith S <aajith@arista.com> net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na

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.
