While the hardware supports 2 Tx and 2 Rx queues we do not have the full implementation in our Linux e1000e driver to support this. The performance to be gained from multiple queues is very small, and was not a requirement for our Linux software. Windows may implement some support, but I'm not sure. So the short answer is its not supported right now, and I doubt it will be implemented for e1000e as there is likely to be very little benefit. If we get enough customer requests our position could be reconsidered.
