Subject[PATCH] ipvlan: flush arp table when mac address changed
Date
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.
