Subject: i40evf: Allow turning off offloads when the VF has VLAN set
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Patch-mainline: v4.16-rc1
Git-commit: e0f60a815cb3505c37620048568553f82ee159ba
References: bsc#1101816 FATE#325147 FATE#325149
This patch adds back the capability to turn off offloads when VF has
VLAN set. The commit 0a3b4f702fb1 ("i40evf: enable support for VF VLAN
tag stripping control") adds the i40evf_set_features function and
changes the 'turn off' flow for offloads. This patch adds that
capability back by moving checking the VLAN option for VF to the
next statement.
