Submit #2780: [PATCH] Optionally allow IPv6 ND packets from non-neighbours

* Author: gpr
* Status: Closed
* Priority: Normal
* Assignee: 
* Category: Networking
* Target version: 
IPv6 code discards ND packets from non-neighbours, which is believed to be correct, but breaks ND on some configurations (VULTR ipv6 for example). Hence the patch, it makes this behaviour optional (via sysctl). Default is old behaviour (discard those packets), accepting such ND packets can be insecure.
