From c3262d9deccaa7e796b0145b2d26f53c0e2d178f Mon Sep 17 00:00:00 2001 From: Mahesh Bandewar Date: Wed, 18 Jan 2017 15:02:53 -0800 Subject: [PATCH] ipvlan: use netdev_is_rx_handler_busy instead of checking specific type IPvlan checks if the master device is already used by checking a specific device (here it's macvlan device). This is technically not sufficient and it should just ensure the rx_handler is busy or not. This would be a super check that includes macvlan and any other that has already registered rx-handler.
