I've found it. Thanks! Is there any reason not to merge the igbvf-part of promiscuous mode support upstream? It won't do harm and allows the PF driver (which does not need to be the stock Linux PF driver) to make the final decision. In short: It would make our lives a bit easier here[1]. ;) Just curious: Why does the PF driver in 2.6.35 handle multicast promiscuous mode?

I didn't think of the second issue, but your obviously right. This shouldn't be a problem for us, since we enforce exact filtering for VFs that aren't promiscuous.
