Subject: Revert "rtnetlink: Do not generate notifications for CHANGEADDR event"

From: David Ahern <dsahern@gmail.com>


[ 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.

Fixes reported regression:
