From 6eb7939371104e4ff78261c165c6f33ff6d90031 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 8 Aug 2017 15:51:02 -0600 Subject: net: ipv6: lower ndisc notifier priority below addrconf ndisc_notify is used to send unsolicited neighbor advertisements (e.g., on a link up). Currently, the ndisc notifier is run before the addrconf notifer which means NA's are not sent for link-local addresses which are added by the addrconf notifier. Fix by lowering the priority of the ndisc notifier. Setting the priority to ADDRCONF_NOTIFY_PRIORITY - 5 means it runs after addrconf and before the route notifier which is ADDRCONF_NOTIFY_PRIORITY - 10.
