According to the current implementation, all VFs will set bit IXGBE_VMOLR_ROMPE during initialization, this cause any VF will accept packets that match the MTA table. Since the MTA table is shared by all VFs which means if one VF update MTA table in function ixgbe_vf_set_multicast, then all other VFs will receive multicast packets which cause unnecessary performance overhead. So it's better to set VF's ROPE bit of register VMOLR only if multicast address filter is required on that VF. Also, the ROPE bit should be reset when multicast address filter is requested to clean. This patch also aligns to the related fix on ixgbe kernel driver 5.3.7.
