4.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: David Ahern <dsahern@xxxxxxxxx> [ Upstream commit 3753654e541938717b13f2b25791c3171a3a06aa ] This reverts commit cd8966e75ed3c6b41a37047a904617bc44fa481f. The duplicate CHANGEADDR event message is sent regardless of link status whereas the setlink changes only generate a notification when the link is up. Not sending a notification when the link is down breaks dhcpcd which only processes hwaddr changes when the link is down.
