There was a workaround partially implemented for the 82576 that is needed in order for VLAN tag stripping to function correctly. The original code had side effects that would make it so the workaround was active on all MACs. I have updated the code so that the workaround is enabled, but limited to the 82576, or activated if we exceed the available unicast addresses. The workaround has a side effect of mirroring all of the traffic outgoing from the VFs back to the PF. As such it is not recommended to use the 82576 in promiscuous mode as it will take a performance hit, though this is now consistent with the performance as seen on the out-of-tree igb driver. I also limited the scope of the UTA bits all being set to only when the VMOLR register is enabled. This should limit the effects of the UTA register so that we don't pick up any excess traffic unless promiscuous mode has been enabled on the PF, whereas before the PF would have ended up in something equivalent to unicast promiscuous mode with VLAN filtering otherwise.
