From ab452c3ce7bacb27ffe2fc0144aecd0c399e1e24 Mon Sep 17 00:00:00 2001 From: Keefe Liu Date: Mon, 14 May 2018 19:38:09 +0800 Subject: [PATCH] ipvlan: call netdevice notifier when master mac address changed When master device's mac has been changed, the commit 32c10bbfe914 ("ipvlan: always use the current L2 addr of the master") makes the IPVlan devices's mac changed also, but it doesn't do related works such as flush the IPVlan devices's arp table.
