From 609bbe15e301dbfef6964359f4cbead2a5daba5d Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 3 Apr 2018 17:16:25 -0400 Subject: [PATCH] macvlan: Add function to test for destination filtering support This patch adds a function indicating if a given macvlan can fully supports destination filtering, especially as it relates to unicast traffic. For those macvlan interfaces that do not support destination filtering such passthru or source mode filtering we should not be enabling offload support.
