Subject: [PATCH v2] ipvlan: flush arp table when mac address changed
Date: Mon, 14 May 2018 17:22:56 +0800 [thread overview]
Message-ID: <20180514092256.10940-1-liuqifa@huawei.com> (raw)
From: Keefe Liu <liuqifa@huawei.com>
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 flush the IPVlan's arp table.
