From: Alexander Duyck Date: Tue, 3 Apr 2018 21:16:30 +0000 (-0400) Subject: macvlan: Provide function for interfaces to release HW offload X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=53cd4d8e4dfb231fa5ba125b6c0666b82a0504fa;p=linux.git macvlan: Provide function for interfaces to release HW offload This patch provides a basic function to allow a lower device to disable macvlan offload if it was previously enabled on a given macvlan. The idea here is to allow for recovery from failure should the lowerdev run out of resources.
