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


From: Ivan Vecera <cera@xxxxxxx>

[ Upstream commit 6d928ae590c8d58cfd5cca997d54394de139cbb7 ]

BE3 VFs without FILTMGMT privilege are not allowed to modify its MAC,
VLAN table and UC/MC lists. So don't try to delete MAC on such VFs.
