Rather than to my NIC, I wanted to say that my solution can be related to
improve the packet filtering for not dropping the
packets in the NIC after changing vlan's MAC, my fault. Anyway you previous
experience is a good hint for me, thank you for
sharing it.

However, I won't be able to perform concrete tests on this side once this
easter weeekend passes and I have the time,
so by now I can only speculate.
