4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Schmidt <mschmidt@xxxxxxxxxx>
[ Upstream commit 83bd9eb8fc69cdd5135ed6e1f066adc8841800fd ]
VFs are currently missing the VLAN filtering feature, because we were
checking the PF's acquire response before actually performing the acquire.
Fix it by setting the feature flag later when we have the PF response.
