Subject: macvlan: use netdev_is_rx_handler_busy instead of checking specific type
X-Git-Tag: v4.14-rc1~1463^2~362^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=322dc6e067a15a17e66ce35338ca701f13c6422d;p=platform%2Fkernel%2Flinux-rpi3.git

macvlan: use netdev_is_rx_handler_busy instead of checking specific type

netdev_is_rx_handler_busy() check is a superset of netif_is_ipvlan_port()
check and hence should be preferred.
