[PATCH 4.7 61/69] ixgbe: Re-enable ability to toggle VLAN filtering

[Greg Kroah-Hartman]

4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexander Duyck <alexander.h.duyck@xxxxxxxxx>

commit 3d951822be216d8c6fcfc8abf75e5ed307eeb646 upstream.

Back when I submitted the GSO code I messed up and dropped the support for
disabling the VLAN tag filtering via the feature bit.  This patch
re-enables the use of the NETIF_F_HW_VLAN_CTAG_FILTER to enable/disable the
VLAN filtering independent of toggling promiscuous mode.

Fixes: b83e30104b ("ixgbe/ixgbevf: Add support for GSO partial")
