From 53cd4d8e4dfb231fa5ba125b6c0666b82a0504fa Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 3 Apr 2018 17:16:30 -0400 Subject: 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.
